· The customer must establish protocols to prevent persons with cardiac pacemakers, neurostimulators, and biostimulation devices from entering magnetic fields of greater than 5 gauss (exclusion zone).

· Main power transformers must remain outside the 3 gauss field. EMI < 40mG RMS AC at the magnet location.

EMI <9.39mG DC.

· Potential exists under fault conditions that the 5 gauss line may expand radially to 11.48 ft. [3.5 m] and axially to 14.76 ft. [4.5 m] for 1 second or less. It should be noted that normal rampdowns or magnet rundown unit initiated quenches will not cause the magnetic field to expand.

· It is recommended every site consider the event of a quench and plan accordingly (such as placing 5 gauss warning signs at expanded locations).

· The ferrous metal objects listed below must not move into or inside of the moving metal sensitivity line during scans.

Please refer to pre-installation checklist in pre-installation manual listed on the cover sheet for items critical to image quality.

1. The layout should be arranged so that the 5g line is contained to the magnet room. If not possible, a barrier is recommended to prevent entry to the 5g field area.

2. The spaces around, above, and below the magnet must be reviewed for effects of the 5g, 3g, 1g, and .5g fields.

Refer to the proximity limit chart in the MR pre-installation manual referenced on the cover sheet.

3. For moving metal, the restriction lines typically extend outside of the MR space. Please confirm there are no moving metal concerns within these areas.

4. For vibration, analysis to be completed as required per pre-installation manual.

5. For EMI, review the site for the location of the main electrical feeders, AC devices, or distribution systems. An

EMI study is recommended if large AC systems are nearby.

6. Details of the floor below the magnet must be reviewed. The structural engineer must verify that the quantity of steel in the volume 10ft [3.1m] x 10ft [3.1m] x 13in [.3m] deep (below the magnet) does not exceed the allowable steel content as given in the MR pre-installation manual referenced on the cover sheet.

7. Remove, cover, or fill-in abandoned ducts or troughs from the Equipment and Magnet rooms. Access/computer room flooring in the Equipment room can either be removed or assessed and reinforced to support heavier cabinets.

Responsibility for the coordination, design, engineering, and site preparation resides with the customer and their project architects and contractors. GE does not, by providing reviews and furnishing comments and assistance, accept any responsibility beyond its obligations as defined in the MR system, sale/purchase agreement.

MRI SITE PLANNING REMINDERS

Broadband RF noise is a single transient or continuous series of transient disturbances caused by an electrical discharge. Low humidity environmental conditions will have higher probability of electrical discharge. The electrical discharge can occur due to electrical arcing (micro arcing) or merely static discharge. Some potential sources capable of producing electrical discharge include:

· Loose hardware/fasteners vibration or movement (electrical contunuity must always be maintained)

· Flooring material including raised access flooring (panels & support hardware) and carpeting

· Electrical fixtures (i.e. Lighting fixtures, track lighting, emergency lighting, battery chargers, outlets)

· Ducting for HVAC and cable routing

· RF shield seals (walls, doors, windows etc.)

For additional information regarding image quality, refer to the pre-installation manual listed on the cover sheet.

The actual field strength can be affected by Magnetic shielding, Earth's magnetic field, other magnetic fields and stationary or moving metal. This information must be used to evaluate potential site interaction of GE Healthcare equipment with other non-GE Healthcare equipment. Magnetic shielding can be installed to prevent interaction between the magnet and nearby sensitive devices. The GE Healthcare Project Manager of Installation (PMI) can work with the customer to coordinate the magnetic shielding site evaluation. The customer is responsible for installation of all magnetic shielding.

The customer must provide detail defining ferrous material below the magnet to the Project Manager so the GE Healthcare MR Siting and Shielding team can review for compliance.

ISOGAUSS PLOTS

The isogauss contour plots illustrated represent the performance of the system and the steel room shield described in the final shield design dated OCT. 03, 2022. The actual magnetic flux density at any point in the vicinity of the magnet when installed may vary from the contour plots due to factors such as the concentrating effects of nearby ferrous objects and ambient magnetic fields, including the earth's magnetic field. Therefore, the contours shown are only approximations of actual flux densities found at corresponding distances from the magnet's isocenter.

PENETRATION PANEL CLOSET

An enclosure (i.e. closet) must be provided to restrict access to the PEN panels and for storage of excess interconnections.

· The PEN closet must have a mechanical locking mechanism to restrict access to the PEN panels

· The PEN closet must maintain the minimum service area outside the 200 Gauss in the magnet room.

· PEN closet must allow free air exchange of 400CFM (680 m³/hour) between the Magnet room and PEN closet for MR system blowers. Airflow may be achieved through door louvers or other openings in the PEN closet that meet all other PEN closet requirements

A closet service hatch must be provided if the room does not allow the PEN panel blower box removal path to remain completely outside the 200 Gauss line.

NOTE: If the room size is sufficiently large so the SPW blower box can be removed without entering the 200 Gauss line, a closet service hatch is not required.

The closet service hatch must meet the following requirements:

· Must be located within the PEN closet on the RF wall allowing access to the Equipment room

· May be located anywhere within the PEN closet (between 254 [10 in] and 1524 mm [60 in] with unobstructed pass-through)

· Must be minimum 508x508 mm [20x20 in]

· Must maintain RF shield integrity for all service access

· May use any design (quick disconnect RF panel, blanker panel, hinged door, etc.) as long as all other requirements are met

· The closet service hatch removal must take less than 15 minutes (replacement must also take less than 15 minutes)

PERFORMANCE STATEMENT FOR MAGNETIC SHIELD DESIGN SHIELDING PLAN [REFERENCE ONLY-NOT TO SCALE]

ADDITIONAL NOTES

· Attractive force of a magnet on the ceiling and walls of the steel shield will be a maximum of 30% of the shield's weight. Support structure must account for these additional forces.

· Attractive forces on the floor or sub-floor may be sufficient to lift shield's weight. Support structure must prevent this with adhesive or bracing.

· M36 Silicon steel is used in this shield. see shielding requirements sheets for specifications.

All surfaces are 1/8" M36

GE HEALTHCARE ("GE") provides this magnetic shielding design solely for use with GE's Magnetic Resonance System ("System"). This magnetic shielding design applies solely to the magnetic resonance suite configured as shown in this drawing set.

The magnetic shield, shown in this set, when constructed in strict accordance with this magnetic shield design will:

1. Contain the MRI-generated magnetic induction of 5 gauss within 11'-0" plan north of the magnet's isocenter.

("Design Objectives"), subject to and conditioned upon the following:

1. The magnetic field strength measurements are conducted using techniques which account for the effects of the earth's magnetic field and;

2. The magnetic field strength measurements are conducted using techniques which account for magnetic field distortions caused by magnetic materials in the vicinity of the measurement and;

3. Customer demonstrates to GE that the shielding material and fabrications are in strict accordance with GE's design and specifications and;

4. Customer demonstrates to GE that the shielding is installed in strict accordance with GE's design, specifications and requirements and;

5. Customer demonstrates to GE that (i) the System has not been and is not being subjected to improper or extraordinary use, (ii) the System has not been and is not being subjected to improper maintenance, and (iii) Customer has complied with all applicable instructions or recommendations of GE related to the System and magnetic shield; and

6. Customer operates the System at or below its specified field strength.

GE will re-perform the magnetic shielding design services, to the extent that GE determines the design services fail to meet the Design Objectives specified above, provided GE is notified in writing by Customer of such failure within one (1) week after the date of availability of the System for first use, subject to all other terms and conditions of the agreement between GE and Customer for the purchase or lease of the System.

The foregoing sets forth Customer's exclusive remedies and GE's sole liability for claims based on the failure of the magnetic shielding design services to meet the Design Objectives. In no event shall GE be liable for special or consequential damages.

The magnetic field gradients resulting from the magnetic shield's effect on the System's magnet will allow the System's magnet to meet published homogeneity specifications upon completion of required installation procedures.

The final performance of the magnetic shield set forth in this drawing set depends on strict adherence to the construction and material requirements detailed herein. Any deviation from these requirements will degrade shielding effectiveness. For this reason, GE recommends that only established magnetic shielding vendors be used. Vendors should be required to provide documentary evidence to demonstrate that their shielding product complies with GE's construction requirements, material requirements, chemical composition specifications, and annealing specifications; or the material's DC magnetization curve at high induction is equivalent to GE's specification on SH2.. A guarantee that the finished shield will meet the Customer's fringe field containment requirements should be sought from the shielding vendor.

The isogauss contours shown on this drawing set indicate the magnetic fringe field containment which corresponds to the predicted interaction between the System and the magnetic shield design described. GE creates these isogauss contour plots only to predict if the shield design meets the Design Objectives. All other effects such as the superposition of the earth's magnetic field, residual magnetism, and localized field concentration effects, due to ferromagnetic structural elements, are not considered or indicated. The exact location of a particular isogauss contour may differ from that shown due to: (1.) the above stated reasons and (2.) the resolution limits of the mathematical modeling techniques used to derive these results. Note also that for actively shielded Systems, fault conditions may exist where the isogauss contours expand temporarily (refer to your System's Pre-Installation Manual for exact information regarding fault expansions).

The Customer is responsible for the effect of the fringe fields produced by the System's magnet, and is responsible for the coordination of the magnetic shield design into existing or planned facilities, such as foundations/footings and other building components.

The Design Objectives have been formulated by GE from information, both written and verbal, obtained from the Customer, his agents, and/or representatives as part of the MR Site Evaluation process. The final decision on the Design Objectives criteria and the amount of magnetic field containment needed at this site rests solely with the Customer or his designated representatives. Please contact MR Siting/Shielding immediately with any corrections and/or additions related to this magnetic shield design.

GE recommends that your final shield fabrication drawings be forwarded for review. Any deviations from the design specified in this drawing set must be brought to the attention of GE. Please allow up to two weeks for the review process.

Send drawings to your Project Manager as identified on the cover sheet.

FABRICATION

1. The design of the shield support system is the responsibility of the customer's architect, structural engineer, and shield vendor.

2. The magnetic shield design must be adhered to exactly. Any deviation from dimensional design, fabrication technique or material specification must be assessed and documented by GE MR Siting.

3. Building and shield support structures should be outside of the steel plates to preclude detrimental effects on homogeneity. If it is absolutely necessary to have support structure on the inside of the shield, a homogeneity analysis must be performed and documented by GE MR siting.

4. For all 1.5T and 3T MR systems, use of non-magnetic materials for concrete floor reinforcement is recommended, unless a homogeneity analysis has been performed and documented by GE MR Siting. For older 1.5T systems with the Magnishield option, signa 0.5T systems, MR Max systems and Vectra systems, conventional reinforcing and structural members are acceptable.

5. A secondary plate must be magnetically isolated from the primary shield. The use of non-magnetic structural members such as aluminum or non-magnetic stainless steel is acceptable.

6. If the magnetic shield is installed inside an RF shield, both the shield and its support system must be isolated from ground by 1,000 ohms or greater and meet all the GE RF room requirements as specified in the appropriate GE pre-installation manual.

7. The minimum finished floor to finished ceiling clearance in the magnet room is shown on sheet A2. Clearance dimensions do not include space required for the magnetic shield, RF shield, shield structure, and finished ceiling materials.

8. Locations of the penetration panel, window, and door openings are established on the final layout. Changes must be documented by GE MR Siting and Planning.

9. Penetration panel mounting details are specified in the appropriate GE site planning direction.

10. Consult GE MR Siting for guidance on any issues relating to magnetic shielding.

11. There must be a minimum of 8 inch [200mm] between the magnetic shield and the area where the magnetic field is being reduced. For example if a hallway has a 5 gauss restriction goal, the magnetic shield should be positioned 8 inch [200mm] inside the hallway surface. Larger buffer spaces are preferred but 8 inch [200mm] is the recommended minimum.

12. If the magnetic shield is supported by the parent room structure, the parent room structure should be wood/concrete/aluminum whenever possible. If the parent wall structure is steel, then the magnetic shield needs to be decoupled from the steel studs by a minimum of 5/8 inch [16mm] gypboard, plywood, furring, or other non-magnetic media.

13. If the magnetic shield is supported inside the RF structure, care must be taken to avoid loose metal to metal contacts or dissimilar metal contacts. Refer to the RF section of the pre-installation manual for all requirements. Magnetic decoupling media may also be needed if the magnetic shield is attached directly to an RF shield that is primarily steel.

1. Magnetic shield ceilings, floors, walls, etc. Will consist of multiple layers to make of the design's required thickness.

2. Slotted or oversized bolt holes are recommended to assure adequate play for positioning plates tightly together. Refer to detail a.

3. If multiple layers of steel are used, some lapping plates can be eliminated by staggering plate separations. Refer to detail B. This is the recommended method for multiple layers.

4. If layers are not staggered or a single layer of the required thickness is used, lapping plate must be used to cover plate separation. Lapping plate is required at each corner, plate separations perpendicular to the magnet bore's axis. This include all vertical seams in the sidewalls, all cross seams in floor and ceiling, all horizontal and vertical seams in the front and rear surfaces and all corners where a front or rear surface meet any other surface. Refer to details C, D, E, F, and shield isometric.

5. Gaps in the shield which are perpendicular to the flux path are critical and should be kept to a minimum. Maximum separation between plates is 1/8 inch (3mm).

6. Hole diameter of 8" [200mm] or less, when separated from another hole by a minimum of 3 times the diameter of the hole is allowed as needed. Holes for cryogen venting, HVAC, etc. Must be assessed and documented by GE MR Siting.

7. Angled joints do not need to have beveled mating edges. Refer to detail E.

8. When lapping plate material is required, it should extend at least 3" [76mm] to each side of the separation, and should have a total minimum thickness of 1/3 the thickness of the shield thickness.

9. Any separation between plates which exceed 1/8" [3mm] cannot be corrected by placing a lapping plate over the separation or using full seam welds across the separation. Corrections for this situation must be assessed and documented by GE MR Siting.

10. Lapping plate can be attached by tack welding or bolting.

11. Shield plates are to be free of loose scale. Failure to remove scale can result in loose scale and steel particles becoming lodged in the magnet.

The preferred method for removal of scale is sandblasting. Removal of scale using wire brush is permitted. Shot blasting is prohibited.

12. Shield plates must be rigidly supported to prevent movement resulting from air pressure or other environmentally induced changes which can alter the magnet's homogeneity or systems performance.

13. Shield plate must be well anchored to the support structure by plug welding or bolting.

14. Full seam welding is not recommended for attaching shield plates to support structure or adjacent shield plates.

15. Minimum penetration full seam welds are allowed when the magnetic shield also serves as the RF shield.

16. Full seam welding is not allowed on silicon steel sheets.

17. Minimize the need for flame cutting of steel plate after annealing, as material's magnetic properties can be altered as a result of stress induced by this process.

18. Loose ferrous components become dangerous projectiles when the magnet is energized.

The actual performance of the magnetic shield depends upon strict adherence to the following requirements.

MAGNET STEADY-STATE VIBRATION SPECIFICATIONS

VIBRATION SPECIFICATIONS

Excessive vibration can affect MR image quality. Vibration testing must be performed early in the site planning process to ensure vibration is minimized. Both steady state vibration (exhaust fans, air conditioners, pumps, etc.)

and transient vibrations (traffic, pedestrians, door slamming, etc.) must be assessed.The Magnet cannot be directly isolated from vibration. Any vibration issue must be resolved at the source.

Transient vibration levels above the specified limits in the MR Site Vibration Test Guidelines must be analyzed. Any transient vibration that causes vibration to exceed the steady-state level must be mitigated.

· All units that are wall mounted or wall supported are to be provided with supports where necessary. Wall supports are to be supplied and installed by the customer or his contractors.

· Dimensions are to finished surfaces of room.

· Certain MR procedures require an extremely stable environment to achieve high resolution image quality.

Vibration is known to introduce field instabilities into the imaging system. The vibration effects on image quality can be minimized during the initial site planning of the mr suite by minimizing the vibration environment. See PROXIMITY LIMITS, PATIENT TABLE DOCK ANCHOR MOUNTING REQUIREMENTS AND VIBROACOUSTIC DAMPENING KIT details for additional information.

· Standard steel studs, nails, screws, conduit, piping, drains and other hardware are acceptable if properly secured. Any loose steel objects can be violently accelerated into the bore of the magnet. Careful thought should be given to the selection of light fixtures, cabinets, wall decorations, etc. To minimize this potential hazard. For safety, all removable items within the magnet room such as faucet handles, drain covers, switch box cover plates, light fixture components, mounting screws, etc. must be non-magnetic. If you have a specific question about material, bring it to the attention of your GE project manager of installations.

· Floor levelness refer to MAGNET ROOM FLOOR SPECIFICATIONS DETAIL, this floor levelness requirement is important for accurate patient table docking.

· Non-movable steel such as wall studs or hvac components will produce negligible effect on the active shield magnet.

· Customer's contractor must provide all penetrations in post tension floors.

· Customer's contractor must provide and install any non-standard anchoring. Documents for standard anchoring methods are included with GE equipment drawings for geographic areas that require such documentation.

· Customer's contractor must provide and install hardware for "through the floor" anchoring and/or any bracing under access floors. This contractor must also provide floor drilling that cannot be completed because of an obstruction encountered while drilling by the GE installer such as rebar etc.

· Customer's contractor to provide and install appropriate supports for the storage of excess cables.

· It is the customer's responsibility to perform any floor or wall penetrations that may be required. The customer is also responsible for ensuring that no subsurface utilities (e.g., electrical or any other form of wiring, conduits, piping, duct work or structural supports (i.e. post tension cables or rebar)) will interfere or come in contact with subsurface penetration operations (e.g. drilling and installation of anchors/screws) performed during the installation process. To ensure worker safety, GE installers will perform surface penetration operations only after the customer's validation and completion of the "GE surface penetration permit"
