Dear Kristen:
As you know, we have now received approval for our MRI project from both the
PEC and DRB. l.le subnitted the appljcation for a building permit last week,
and were given verba'l approval by Mike Whitaker to proceed with demolition
work.
After talking with Gary Murrain this morning, I understand that the plans arecurrently being reviewed by the zoning staff. Gary also stated that his
department has a significant backiog of plans awaiting code checks, and thatit might be several more weeks before he could issue a building permit, whichis, of course, needed before we can begin to place new work.
In the case of the MRI, some disruption of the main lobby, business office
and corridor connecting the nain lobby with the emergency room lobby is
unavoidable. It is our intention to restore these areas to normalcy by ski
season, and we believe that attainment of this goal will benefit the hospital ,
and the entire community it serves. However, we cannot begin to strive for
this goal until a building permit is issued.

Dear Kristen:
Bob Lazier has approved our use of the the temporary parking 1ot immediately
west of the Sun Vail condominiums until our new parking structure is completed
on 21 December 1990, This lot is the same one the PEC approved for temporary
use last year. Availability of this'l ot wil'l enable us to provide the 272
spaces requ'ired to support those porti ons of the hospi tal presently i noperation. Thjs total does not jnclude the 19 spaces required to support the
MRI or Learning Center, sfnce neither of these projects will be completeduntil early 1991.
Ihe 272 spaces will be provided as follows:
Self-parking west lot 65 spaces
Valet parking west lot L07
Anbulance garage 3
Surface park'ing east of
ambulance garage 7
Manor Vai'l Lodge 60
Sun Vail Lot 30Z spaces
l,le will re-vegetate the Sun Vail Lot next spring.

I. DESCRIPTION OF PROPOSED USE
The Vall Valtey Medical- Center is located in the Public Use
zone diEtrict and any expansion in this district requl.res aconditional use review. The hoepital is requesting a
conditional use perrolt to lnstall a magnetlc reeonance
lnaging (!aI) system later thJ-s year. A t{RI is a
conputerized system that uses a nagnetic field and ordinary
radio waves to produce irnages (or scans) of soft tisEuesthat assist physicians in dLagnosing soft tissue inJuries.
The request includes:

I
IT. CRITERIA AND FINDINGS
Upon review of Section 18.60, the Cornmunity Developnent
Departnent recommends approval of the conditional use pernit
based upon the following factors:
A. Consideration of Factors:
1. Relationship and irnpact of the use on developmentobiectives of the Town.
The addition of the ltRI unit is positive as it
complements existing medical services on the site.It makes sense to consolidate nedical services inthis site as long as parking and other developrnent
standards can be met.
2. The effect of the use on light and air.distribution of population, transportation
faeilities, utilities. schools, parks andrecreation facilities, and other oublic facilities
needs.
This expansion should have no significant inpacts
on these factors.
3. Effect upon traffic with particular reference to
congestion. automotive and pedestrian safetv and
convenience, traffic flow and control . access,
maneuverabilitv. and removal of snow fron thestreet and narkinq areas.
The following chart summarizes the parking
allocation on the hospital site given this
expansion.

* These calculations recognize the six fewer daytine enployees
as explained in Dan Feeneyrs attached letter dated June 25, 1990.
The hospital rrresunreyed staff projections and found that the
actual number of ernployees anticipated is slightly lower than
initially projected in 1988.rt
** six spaces have been approved by the hospital and Town Councllto neet the parking reguirements for the Vail National Bank. Apotential total of 12 spaces rnay be used by the Bank in thefuture. The Bankrs use of any additional parking in the wMc
structure for future expansions will require Town of Vail PEC
and/or Council approval . At this tirne, the Council has statedthat all future expansions of the Vail National Bank Buildingwlll require parking to be located on Bank property. For
planning purposes, staff felt it ltas appropriate to consider the
12 spaces in the WUC structure to avoid a potential parking
deficit. This consideration of the 12 spaces is not neant to
indicate any type of approval to actually use all 12 spaces.
deficit
The chart above lndicates that after thls
expanslon there will be a 4 space surplus ofparking ln the lIVlilC etructure. The seqond columnof flgrures indicates that 50 spaces would beavailable if the learnlng lab Ln the parking
structure is converted into parking ln the future.
IsEue of Lot 10 Parkino
fn April of 1990, the VaIl Valley Medical Center
requested a conditional use permit to expand theparking etructure by two 1rl2 levels. The requestalso Lncluded a learning center lab which would belocated in the lowest level of the parklngstructure. ttro break-out panels are Lncluded inthe structure to connect to the adJacent
Doubletree parking. During thLE review, the
Plannlng Connission expressed sone concern aboutthe hospltalrs reliance on the 18 parklng spaces
located on Iot 10. This lot ls owned by the Townof VaiI and is located on the southnest corner ofthe VVtrlC parklng lot adJacent to l{est MeadowDrive.
The hospital , through a lease agreement with the
Town, has the right to use 18 parking spaces.
According to the agreement, rrthis lease shall be
autornatLcally renewed for subsequent I year terms
unlesE elther party gives wrltten notice to theother of its intent not to renew no later than 60
days prlor to the end of the lease tern.rr The endof the lease tem is April 30th of each year.
The Pl.anning staff is also in the early stages of
developing a design for West lteadow Drive to allowfor better pedestrian access and safety as well as
irnproved emergency and auto traffic flov. It nay
be necessary to utilize a portl-on of I.ot 10 to
accommodate tbese design inproveuents.
staff believes it lE reaeonable to support thls
expansion of the hospital which requires anaddltional two parklng apaces. However, forfuture expansions, as outlined in Dan Feeneyrsletter dated August 3, 1990, staff reconnends that
the hospital incorporate the 18 spaces on Iot 10into parking on the hospital property. From Dan
Feeneyrs letter dated Augtust 3, 1.990, it appearsthat the future phases of expansLon for thehospltal will be significant and will requireadditlonal parking.
The VWC naster plan includes, per Dan Feeneyf sIetter:
- rAddition of one half level of parking on topof the east side of the Etructure currently
under constnrction. This will provide
dedicated access and parking for a neet
energency roon that we will eventually buildat the east end of our property, wlth accessdirectly off South Frontage Road.
- construction of a detached building at the
west end of our property. Thls facility will
consolidate phyElcianrs offices enabling usto expand hospital departments into space
currently occupled by these functions.
- constructlon of a fourth floor on top of the
west wlng Just cornpleted. This floor will
accommodate additional patl-ent beds, as well
as our pharnacy, laboratory and building
service departments.
- Denolition of the original hospital at the
east end of our property, and construction of
a new bulldlng adjoinlng the south side of
the parking structure currently underway.
Ttris east wing will include additional
parkJ.ng, a relocated main lobby and
idnissions area, a nert energency roon with
vehicular accesa off South Frontagte Road, and
relocated ambulance baYs. tl
staff supports the addition of the MRI facility
and belleves that the two space parking
requirement should not trigger the reuroval of the
I,ot 10 parklng. However, Lt ie inportant to
emphaslze that future expansJ.ons appear to-be rnuch
moie extensLve and wlll have a larger parking
demand. It Is reaEonable to ask the hospital , in
conslderlng future expansions, to also include
parklng to cornpensate for the 18 spaceE on Iot 10.
staff alEo belleves Lt ls positlve that the
hospLtal has etarted an overall naster planning
process for the facllity.

Dear Kristan:
The hospital is requesting a Conditional Use Pennit to install a magnetic
resonance imaging (MRI) system later this year. An MRI'is a computerized
system that uses a magnetic field and ordinary radio waves to produce images(or scans) that are particu'larly effective in diagnosing soft-tissue injuries,
complementing conventiona'l radio'logy ("I-Rays").
As recently as a year ago the hospita1 administration had progranmed an MRIfor 1992-1993. However, the rapid deve'lopment of MRI technology, as well as
the overwhelming acceptance of l4RI scans as a necessary component of the typeof excellent health care we wish to provide, have convinced us that an MRI is
needed now. Pending TOV approvals, we wish to begin construction in September
1990.
Essential features of our application are as follows:
r Construction of approximateWS& square feet on the north side of
the first floor, contiguous with our Emergency Room.
r Construction of approximately 375 square feet on the west side of thefirst floor, inmediately north of the main entry doors.
r,.Jil/81-r Renovation of approximately 1200' square feet of
administrative space, to accomnodate business office personnel being
by the MRI.
r Installation of a sate'llite t(sh 96 the third-floor roof, to transmit
some of the MRI scans to an off-site lHi'litv for interoretation. The dishwill be 8 feet in diameter, and screendd\rom-view. See'attached catalog cut
sheet.
The proposed MRI unit will reguir(tbparring spaces to accommodate two new
day-time employees, one a receptioniltf the other a technician.

Parking requirements for the expansion presently nearing completion were
computed based on staffing projections made in September 1988. Now that
occupancy is imm'inent, we have re-surveyed staffing projections with our
respective departmental managers and found the the actual figures anticipated
are actually slightly 'lower than initia'lly thought:
DEPARTMENT STAFF PROJECTIONS STAFF PROJECTIONS NET REVISION--ffiErEitB- -JmtrEm"-

ToTAL 49 43 - 6
Thus, referring to Page 3 of your 7 March 1990 memorandum to the P.E.C.,
actual parking required to support the third floor expansion is 272 spaces, byvirture of the six fewer daytime employees. A comparison of the actualfigures for the existing hospital , as wel I as expansions currently in progress
or proposed, is as follows:

Dear Kristen:
Fo'l'lowing is a synopsis of the hospita'l 's master plan, presented in the
sequence we feel is most probable. Like a'|1 naster plans, it wil'l be subjectto frequent review and possible revisions to scope and sequence. The synopsisdovetails with drawings prepared by Page Southerland Page, previously
submitted to you.
o Construction of approximately 1600 square feet of new space at groundlevel on the north and west side of the west wing, for housing a magnetic
resonance imager (MRI). The application for a conditional use permit has been
submi tted.
r Addition of one ha'lf 'level of parking on top of the east side of thestructure currently under construction. This wi'l I provide dedicated access
and parking for a new emergency room that we will eventually bui1d at the east
end of our property, with access directly off South Frontage Road.
r Construction of a detached building at the west end of our property.This facility will consolidate physician's offices enabling us to expand
hospital departments into space currently occupied by these functions,
r Construction of a fourth floor on top of the west wing just
completed. This floor wil'l accommodate additional patient beds, as well as
our pharmacy, laboratory and building service departments.
o Demolition of the original hospital at the east end of our property,
and construction of a new building adjoining the south side of the parking
structure currently underuay. This east wing will include additional parking,a relocated main lobby and admissions area, a nev{ energency room with
vehicular access off South Frontage Road, and relocated ambulance bays.
0ther than the MRI unit, the scheduling for these various phases has not been
detenni ned.

PREFACE
This document is designed to be of assistance to architects, consulting engineers and all
conccrned with planning the installation of a Philips GYROSCAN T5 MR imaging system.
Becausc of thc tcchniques used in an MR imaging system, it cannot be installed in any
?l.t!ng building without certain modifications to that building. The magnetic field, the
RF signals, and the cryogenic liquid used all place specific demands on the environment in
which the system is to be installed. Thc system has an impact on its environment, and the
cnvironment in turn has an impact on the system. These are the primary considerations on
which the dcsign of an exarirination area must be based.
This document summarizes the principles on which MR imaging systems operate, indicates
the special requiremcnts involved and suggests possible solutions. Wherever possible, hard
data are provided, but the installation of such a system is always a special case dependent
on local conditions. For this reason, Philips Medical Systems arc always preparcd to offer
detailed advicc on specific proposals.
An M R system ccinsists of a number of subsystems, each of which makes its particular
demands on the envifonment. tn addition, physicians, assistants, patients and service engi-
neers must havc different degrees of access to the equipmerit, For these reasons, a complete
installation nofmally occupies a number of separate but contiguous rooms, each dedicated
to a particular function. The equipment typically installed in each of these rooms, and. any
specific requirements or- recommendations are described.
This guide is applicable for the GYROSCAN T5.onty.
In addition to thc special requirements of GYROSCAN T5 systems, which are described in
this book, all the normal requirements of a modern clinical examination centrc apply. These
include the prescnce of an adequate floor construction, application of anti-static finishes to
b.uilding surfaccs, non-dare illumination in rooms used for video monitors, fire escape routes,
thc provision of furniture for patients and staff, etc. These are considered to fall within the
field of normal hospital design.

PRINCIPLES OF THE MR TECHNIQUE
Magnetic Resonance (MR) or NMR as it is known to physicists, is an established analytical
tcchnique, and has becn in laboratory use for many years. lts application to visualize details
within thc human body is more recent. lts results are comparable with those of Computed
Tomography (CT) cxaminations using X-radiation, but all rescmblance ends there. No
ionizing radiation is used: the process depends on a combination of strong magnetic fields
and radio frequency (RF) signals.
1.1 Magnetic Resonance
The basic principle is that thc nuctei of some chemical elements, when subjected to a
constant magnetic field, have a resonant frequency which is characteristic of that element.
The rcsonant frequency of an element is directly proportional to the strength of the applied
field. This means that if an RF signal of that characteristic frequency is applied in the
Prescnce of a magnetic ficld, the nucleus concerned will absorb energy and move to a higher
energy level. When thc applied RF field is rcmoved, the nucleus will return to its normal
energy level, and thc cncrgy absorbed will be emitted at the same characteristic frequency.
(Tuning forks and pendulums are also examples of resonant objects).
Thus, in addition to a magnetic field, which must be constant, homogeneous and known,
an RF transmitter and receiver are required first to pump energy into the nucleus to excite
it, and then to detect the energy emitted by the nucleus as it returns to its normal state.
The nuclius of most interest at this moment is that of hydrogen, (the proton) since it gives
a strong, well-defincd response.
Hydrogen is extremcly useful since it is abundant in the human body.
The excellent soft tissue-contrast in the images is the result of several para meters. In
particular, tumour tissues can be clearly distinguished with MR. A remarkable feature of
MR images is the absence of artefacts caused by bone structures, and this contributes
ie
I
greatly to their clarity.
1.2. SIGNAL PROCESSING
1.2 Signal processing
The RF response in MR is low. Therefore the signal-to-noise ratio is also inherently low.This problem is overcome by thc use ot. .rriinlind:veraging technique, on the principrethat whereas meaningfur signars wiil bc added, nlise, being random in nature, wi1 tend tocancel itself out duilng the summing and averaging process.
Thc signal emitted by the nuclcus is in fact a complex of signals each of different amplitude,frequency and phase, and is apparcntty incotreieil..lt canlhowe""i, ["lr.rned to yield aseries of discrete sine waves containing meaningful inform.,i.". ii. pr*e-ss is mathematicaland is known as Fouricr Transform An'arvsis. wnit. ti.pt.i; il; iilrli.uori.rs processand it was not until thc, advent "l.t: high-speed .o.prt"i .n'i or'*-"rlla.u"roped FastFouricr Transform algorithms that MR uo""?"'.-ir."ticar techniquc for chemical analvsis.
1.3 The superconducting magnet
The high magnetic fields required are generated by a superconducting magnet: an erectro-rnagnet with wind.ings. of a speciar ailo/that is kept at a very row temperature by immersiohin a container of liquid helium.

SAFETY ASPECTS
The Philips GYROSCAN MR imaging system should preferably only be used in a location
with provisions in compliance with the relevant national and/or international legislation and
recommendations concerning electrical safety in rooms used for medical purPoses, e.g. U.S.
National Electrical Code, VDE or IEC Standards, concerning provisions of an additional
protective earth (ground) terminal used for equipotential connection,
The GYROSCAN T5 is designed and manufactured according to the lnternational Standard
for Medical Equipment the IEC 601.1. and UL 187.
The GYROSCAN T5 is not specified as A.P. (Anaesthetic Proof) equipment, which is re-
quired for thc use of flammable anaesthetics. Non flammable anaesthetics can be used.
In some countries regulations do allow the use of flammable anaesthetics if sufficient re-
freshment of air is provided. In that case, approval by authorised testhouses is neiessary
to establish compliance with local regulations, both for the examination room and the MR
system as the use ofiammable anaesthetic gasses is the official responsibility of the hospital.
Remember that some disinfectants vaporize to form explosive mixtures, and that if such
disinfectants are used, thc vapour must be allowcd to disperse before the equipment is
returned to use.
2.1 Magnetic safetyr
It is the responsibility of thc hospital that the following safety recommendations are followed.
In a well-organized MR-facility with a high degree of discipline of the hospital staff, metal
detection may help to improvc the safety in the magnetic field, but discipline of the hospital
personnel is more important.
Persons having a pacemaker, neu rostim ulator; insulin pump or other biostimulation
device must not be examined with an MR imaging system.
Such persons must stay outside a "controlled zone" with a magnetic field strength of
more than 0.5 mT (= 5 Gauss).
Persons with implants consisting of ferro-magnetic material, such as surgical clips,
artificial cardiac valves and prosthetics or metal splinters, must not be brought into a
stfong magneticfield, and therefore may_not be examined with an MR imagingsystem.
I
10 CHAPTER 2. SAFEW ASPECTS
lron or other ferro-magnetic objects, such as scissors, tools, gas-bottles, vacuum dean-
ers and iron sttetchers, must not be brought into the neighbourhood of the magnet
and thus be kept outside the examination room. Such objects will be attracted by the
magnet and may injure the patient or staff andf or damage the equipment.
Information on magnetic carriers such as floppy disks, disks; tapes and magnetic strips
on credit cards can be erased by thc magnetic field.
A safe limit is I mT (= l0 Gauss) magn€tic field strength.
During site planning, design and construction phases for Philips GYROSCAN T5 MR
systems, a controlled zone having a magnetic field strength of morc than 0.5 mT (=
5 Gauss) should be defintd.
For safe operation a warning label:
'CAUTION - Magnetic field" can be specified for the area beyond 0.5 mT.
The security procedures at the cntrances of the examination room to prevent that
magnetic objects are brought into the examination room may comprise the use of
metal detection equipment.
The Philips GYROSCAN T5 MR systcm is provided with a magnet emergency rundown
unit with two remote rundown pushbuttons for shutting down the magnetic field, which
should only be used in case of emergencies. Using this magnet emergency rundown
system causcs a rapid shutdown of the magnetic field at the cost of a rapid and
substantial boil-off o{ liquid helium.
In case of any medical cmergency concerning the patient e.g. reanimation, he must
be removed from thc examination room whcn medical instruments are needed for
trcatment.
2.2 Safety with liquid helium
Helium gas is .odourless, non-flammable and non poisonous. During evaporation, a
cold haze is formed. Helium gas will risc to the ceiling. The gas is harmful to health
as it will dilute the oxygen in the air. Always keep the ventilation of the examination
room running. At least a 5 timcs per hour air exchange to the outside is required.
The GYROSCAN T5 system has to be connected to a venting system which prevents
evaporation of helium into the examination room.
Under no circumstances should the magnet be energized prior to installation of the
quench venting and exhaust system.
Under no circumstances should a container with liquid helium be brought into the
magnet area unless it is known that the container is made of non-ferrous material.
Special non-ferrous containers are available from the liquid gas suppliers and must so
be specified and appropriately labelled as non-ferrous containers.

t?.. 2.2. SAFETY WITH LIQUIO HELIUM 11
r Liquid helium is extremely cold and will cause frost bites when in contact with the
human body. Use protective gloves when handling cold metal parts.
r Cryogenic liquids should be handled only by well-trained staff.
r oxygen monitoring, if not obligatory by local regulations, is a highly recommendable
complementary safety device.
ln combination with a powerful vcntilator in the air outlet of the examination room
that is automatically switched on by the oxygen monitor, a highly effective contribution
to thc safety in the examination room is created.

SITE LAY.OUT REQUIREMENTS
The GYROSCAN T5 MR system with its small dimensions and reduced fringe field influence,
often allows the location of the unit in existing radiology departments.
Whenever this can be realised onc should discuss possible integration of existing waiting
rooms, offices and other peripheral facilities with the MR suite.
Therefore only the required floor space for examination, technical and control room is pre-
sented in the two typical and minimum layouts.
4.1 Access route for the magnet
Air tranrportcd magnctr arc providcd with a spccial Absolute Prersure Relicf Valvc (APRV)
on top of thc magnct. Thir valvc must bc rcmovcd bcforc sitc tranrport of the magnct.
'l Rcmark:
Replacing the magnci is an extrem€ evcntuality which should still be considered when de-
signing the RF-enclosure and defning the access route to the site.
An access route for bringing in the magnet from outside the building to the examination
room during the initial installation phase must be provided. Transport openings for passage
of the magnet must be provided in this route:
Corridor: 2.50 m (3.8 ft) width x 2.30 m (7.54 ft) height.
Entrance opening in'walls and RF-shield: 1.75 m (5.74 ft) width x 2.30 m (7.54 ft) height.
Roof opening: 2.50 x 2.50 m (3.8 x 3.8 ft).
This route must be capable of bearing the transport weight of the magnet: 2900 kg
The passage must provide space for manoeuvring and transport devices depending on the
site.
Philips Medical Systems. may provide specialist expertise for bringing in the magnet from
outside the building into the examination room during the initial installation phase .

For the patient support fixations, see drawing Sab: Foundation magnet/patient support
(exa mple).
The magnet is frec standing.
The patient support witl be glued on two floor pads.
ln carthquake areas always consult local expert engineering consultants. For detailed RF
and floor requiremcnts sec chapters 5 and 7.
An Qxternal RF shielding is required for thc examination room. For details see chapter 5:
RF shielding requirements.
The GYROSCAN T5 is delivcrcd with a standard top cover to be combined with a suspended
:,.itil6. Thc resultant ceiling height is then 2.52 m (8.26 ft).
While the cables from the filter box are all to be initalled above the suspended ceiling the
end result is a more comfortable look for patient and staff: turret. cryo-cooler cold heal and
cables will be hidden behind the covers.
Rcrnark:
Apart from the typical lay-out presented on drawing 2ab: Typical lay out, a special execution
is shown in the drawing 3: Minimum lay-out.
This lay'out shows a minimum floor space situation where the magnet is located in a 5 x 5
m (16.4 x 16.4 ft) room.
Be aware that the closer the magnet reaches the examination room walls, the more importantit is to know what hidden metal structures are in the wall construction. Moreover as the0'5 mT (5 Gauss) line will exceed the examination room extra care should be taken. See

RADIO.FREQUENCY SHIELDING REQUIREMENTS
5.1 RF interactions
The GYROSCAN T5 MR imaging system uses RF signals in the 21 MHz. band'
This is within the frequenci t!ig:. J*a for radio coirmunications. As the signals emitted
by the human body arc ";;;.;k, they_can be.disturbed by signals received from radio
communication uquip-"nt or other eleciiical equipment Present in the hospital'
To prevent such environment-to-system intetactions, rigorous R!.yee1inS is required' while
on the other hand, RF r.r.liing ii also required to preJent the MR system influencing other
RF scnsitive equipment in the hospital'
'Notc:
It may happen that strong RF-cmitting cquipmcnt ir uscd in thc dircct ncighbourhood of
thc GYROSCAN T5 that-uscr frequeniier close to 21 MHz- In that casc, contact Philips
Mcdical Systcmr for information and support'
5.2 ExternalRF-shielding
Thc compact dcsign of the GYROSCAN T5, with an cxtremely short magnet, offers highly
appreciative bcnefits. c.g.:
-'Patient friendlyness; pitient's head outside the system during many examinations'
Even during Jread-scans the patient can look out of the system'
- Good patien't-access allowing easy monitoring or assistance of the patient.
These benefits can only be exploited effectively with external RF-shielding of the examination
room.
5.3 Purchasing RF-shielding
I The external RF-shielding is to
by Philips.
Philips will provide on request
be purchased from a supplier, which has been recommended
a list of possible RF-shielding suppliers.

Deiaited requirements for thc RF-shielding are described in the Philips report:
"RF room shielding GYROSCAN T5 Specifications", which is available on request.
5.4 The RF-enclosure
Shiclding matcrial
Only non-ferromagnetic material shall bc uscd for the construction of the enclosure.
Conrtruction
RF-shieldi n g su ppliers offer di{fercnt concePts:
r Modular.
a
All parts havc standardized dimensions. Adaptation to local site requirements by choice
of modules.
Prefabricated
All prefabricated parts havc customizcd dimensions. Adaptation to local site rcquir+
ments by manufacturing all relevant parts based on local site dimensions and iircum-
Stances.
Wall papering.
Tailor-made construction, by gluing shielding material directly onto examination room
walls, ceiling and floor. '
RF-shielding suppliers may not be ablc tot deliver all mentioned concepts, whereas on thc
other hand spccific sitc conditions may cxclude certain concept(s).
Careful siteplanning and cvaluation of RF-shielding suppti.rs capabilities will lead to a suit-
able solution for each GYROSCAN T5 site.
5.5 Magnet inrtallation opening
During installation of the system, thc magnet is the only unit that cannot be transferrcd
through the door with the specified minimum size. Therefore the RF shielding must have
an installation opening for the magnet. This opening will be closed permanently when the
magnet has been brought into the RF-enclosure.
The minimum required wall opening is: 1.75 x 2.30 m (5.74 x 7.54 ft) (WxH).
The minimum required roof opening is: 2.50 x 2.50 m (3.8 x 3.8 ft).
These values are based on dimensions of the magnet: 1800 x 1550 x 2240 mm (WxDxH).
The location of the installation opening will be site dependent:' ;-

Attention shorld be paid to keep the finished floor as close as possible to thc level of the
su rrou nding rooms.
Floor conrtruction
Different tyPes of floor constructions are offered by RF- shielding suppliers:
r Epoxy layered floor.

guarantee conditions and cause extra costs.
Rcmark:
To avoid unwanted spiead of responsibilities it iistrongly recommendcd that thc rf-shielding
supplier is responsibie for the installation of all required provisions and the finishing of the
foom.
5.9 Earthing in the RF-enclosule
The enclosure has to be provided with one central protective earth (PE) bus-bar/terminal.
This PE point shall be connccted to the hospital PE bus-bar by means of a conductor of at
least'16 mmr,
The central earth terminal in thc System Filter Box has to be connected to the PE bus'
bar/terminal of the enclosure by meins of a conductor of at least 16 mm2'
The locations of the enclosure central earth bus bar/terminal and the System Filter Box
shall be selected in such a way that the distance is minimized (<= 1000 mm) and that
there is no seam in the shielding between both earth points.
For potential equalizing purposes all actessible conductors inside the RF-shielding shall be
connected to one of thise two earth'points. The parts of the system shall be connected to
the terminal inside the.System Filter Box. All other items like facilities for heating, water
. supply shall be connected to the enclosure central earth bus bar/terminal.' The impedance between any conductive part and the enclosure central bus bar/terminal
. shall be less than 100 milli-bhm. The protective earth conductor used must be at least 6
mm2.
An earth leakage circuit breaker (ELCB) is not required.
To optimize the shielding performance, "loops" inside and outside the enclosure shall be
minimized.
This leads to the following precautions:
1. The magnet structure,t"tt b" connected to the earth terminal in System Filter Box
ONLY via one dedicated protective earth wire.
2. The magnet shall be isolated from the enclosure (isolating foundation plate included
in Philips' delivery).
3. The patient support shall be isolated from the enclosure (isolating provisions in patient
support structure included in Philips' delivery).
4. The He quench and boil-off feedthrough shall be isolated from the enclosure on both

MAGNETIC SHIELDING AND HOMOGENEITY
The magnetic field extends outside the magnet in all directions and may go beyond the
boundar! of the MR depariment or building. This is called the fringe field region.
lf possibie the 5 Gauss line should be limited to the interior of the examination room.
A detailed knowledgc of a magnet's fringe field and its relationship to surrounding equipment
and activities is an essential part of any site planning and will always be Part of a layout
proposal as a magnetic field plot related to that particular site.
7.1 Magnetic units

7.2 Magnetic interactions
the Tesla (T). The former unit was the Gauss (G)'
a mattef of interest, the earth's magnetic field is
The field generated by the magnet extends over a volume larger than the magnet.
Within thG volume, it can exert large forces on ferro-magnetic objects. The field can affect
the function of magnetically susceptible devices, such as pacemakers, TV monitors, magnetic
data-stora ge devices, etc.
The field can also be distorted by magnetic objects of various kinds:
. steel structural beams, electric motofs and generators, transformers, powerlines etc.
Static and moving ferro-magnetic objects can influence the homogeneity of the magnetic
field, and hence the image quality of the MR system.

the fringe field from that other system at the isocentre of the GYROSCAN T5 system does
not exceed 2.0 Gauss.
lf the fringe field is less than 0.2 Gauss the GYROSCAN T5 can be used in any condition
without special attention. lf the field is between 0.2 Gauss and 2.0 Gauss the GYROSCAN
T5 magnet has to be shimmed again in the case that the other system is off field. This
procedure using the gradients requires a couple of hours.
7.8 Sensitivity to moving magnetized objects
Some models of lifts are highly magnetised and can cause image artefacts when they move
at short distance of the magnet.
Example : Distance lift to magnet
- more than 15 m : no orecautions
- I to 15 m : oossible field variations to be measured at
magnet isocenter to assess the necessity of a
special action. A solution is always
possible.
- 4 to 8 m : measurements required before proceeding with
this site because a special solution
is not always possible
Ferro magnetic objects in the vicinity of an already installed MR system could be magnetized
and cause image artefacts if they move close to the GYROSCAN T5. In case of doubt contact
Philips Medical Systems.
7.9 Sensitivity to.electro magnetic fields
Currents circulating in power lines, large transformers or electro motors near the magnet
can influence the homogeneity and the stability of the field.
To avoid possible disturbances, minimu m_dista nces from the magnet isocentre are:

HELIUM, LIQUID AND GAS
8.1 Cryogenic effects
Care must be taken when handling liquid helium'
Liquid helium boils at approximately 4.2 K (-269oC or -4520F). Any contact between it or
the fresh ly-eva gorated vapours and the skin must be absolutely avoided since severe fiostbite
will occu r.
In rare circumstances superconducting magnets can "quench".
The superconducting alloy of the magnet coil has no electrical resistance at its operating
temperature (4.2 K). However, a very slight increase in temperature above the critical
temperature results in the appearance of electrical resistance, causing the production of a
large amount of heat.
Thi magnet coils can stand this heating, but the liquid helium will rapidly boil-off, and a
large volume of cold helium gas is discharged. (This is called a quench). A venting pipe,
connected to the outside, is required for a safe venting of helium gas.
8.2 Supply of liquid helium
The GYROSCAN T5 magnet is only cooled with liquid He. The magnet does not contain
liquid nitrogen. As the liquid He is boiling off, periodic filling is required. A cryo'cooler is
part of the standard delivery. The magnet is always shipped "cold" (filled with at least 800
liter liquid He).
The quantity of liquid helium required at installation depends on the shipment time. lf
this time is less than 35 days, liquid helium only is required. Refill is even not required if
shipment lasts only a few days and if the cryo-cooler is made operational after the magnet
has been installed. Should the shipment time exceed 35 days, a special procedure has to be
followed involving the presence of a specialist. Please contact Philips Medical.Systems.
The maximum boil-off rates are:

Capacity of the liquid helium vessel in the magnetr
inimum level | 300 ltrs
Maximum level I 1000 ltrs
Helium filling and topping-up are carried out with an isolated syphon included in the delivery,
using helium gas from a cylinder to pressurize the dewar.
Liquid helium is distributed in well-insulated dewars with'a capacity between 200 and 500
litres. The number of refills pet year depends on the type of dewars locally available. Typical
dimensions for such dewars are given in the table.
Use non-ferromagnetic dcwarr only.
The non-magnetic liquid helium dewar must be placed directly alongside the magnet for
filling and topping, so the site layout must include an access route for a liquid helium dewar.
Temporary storage possibilities for dewars should also be considered.
Typical helium-dewar data
These dimensions should be used f6r planning purposes only. Dimensions, weights, etc. may
vary with supplier.
Notc:
Thc width and thc height of thc door in thc RF-cnclorurc ar wclt ac other doors in the
.ccclt routc rhall allow thc parngc of thc hclium dewars used.
8.3 Supply of helium gas
Helium gas is supplied in gas cylinders which are located outside the examination room and
connected via pipework to a helium gas supply system to be located in the examination
foom.
The purpose of the helium gas supply system is to provide helium gas at very low pressure
in order to transfer liquid helium from a dewar into the cryostat and to provide the refill gas
for the cryo-cooler. Most helium dewars are not self pressurizing.

GAS EXHAUST SYSTEM
One exhaust pipe is required.to evacuate discharges of helium gas from the magnet out
of the building. The static helium evaporation and helium dischirge during a quJnch will
exit from the turret via a one way relief valve. The valve prevents ambient air leaking back
into the cryostat. The system must be capable of exhausting the amount of helium gas
(approximate ratio 750:1 expansion from liquid at 4.2 K to gas at robm temperature) that
may result from a magnet quench.
See drawing 28abc: Venting system, details and views.
All venting pipcwotk and hardwarc outsidc thc cxamination room should bc isolated.
The He gas exhaust pipe part inside the RF shielding, together with the interface with the
the RF shielding called "RF feedthrough" (see below) is part of the standard delivery. See
drawing 30ab: Gas exhaust system inside RF shielding.
It is delivered with a driptray for collecting liquid air in the event of a quench. The slope
of the driptray shall be oriented towards the magnet. For safety reasons it is not allowed to
modify the gas exhaust system nor to use own made parts for the quench pipe.
Tfe part of the exhaust pipe, outside the RF shielding is to be supplied locally. The inner
diameter of the pipe outside the room.can also be 100 mm if the total length between the
turret and open patt outside the building is no more than 15 meter and the number of turns
is no more than 4. The diameter must be 200 mm for that part of the pipe between 15
and 25 meter. For a detailed view how this helium exhaust pipe part should be designed see
drawing 29: Gas exhaust system outside RF shielding.
RF fccdthrough
Part of the He gas exhaust pipe is an RF feedthrough. This item is required to pass cold
He gas through the RF enclosure to the outer part of the He outlet.
The RF feedthrough has a built in temperature gradient device, meant to compensate or
slow down excessive cold transfer from the He exhaust pipe to the RF shield itself, durin{
filling or a quench. lt avoids damage of the wall or ceiling during fiiling or a quencn.

16.3. MAGNET HANDLING REQUIREMENTS
16.3 Magnet handling requirements
The megnet must be lifted from the truck using lifting eyes on top of the magnet or the
dcsignated lift areas on the bottom. See Fig. 31 Magnet lifting and transport
The shock indicators placed on the magnet must be checked before unloading the magnet
from the truck in order to define responsa bilities. (The procedure can be found in the
installation manual).
The maximum tilt angle in any direction should not exceed 10 degrees. This has also to be
taken in consideration wheir defining the access route. Tilting the magnet beyond 5 degrees
may induce a rapid release of cold helium vapour.
A set of 4 castor wheels to tranport thc magnet on site ian be rented from Philips Medical
Systems (see section service tools). With this transport set it is possible to transport the
