2 General System Level

2.1 System Level Requirements for Installing into Existing MR Suite

When planning for the installation of this system in an existing GE Healthcare MR suite or a non-GE Healthcare MR suite, all requirements in this manual must be met because these rooms are considered new installations.

1. If the existing MR suite contains a GE system, the vibration environmental assessment must be done using the High Speed (magnetic eld) Stability tool.

NOTE

The customer may have to hire a vibration consultant based on the results of the analysis.

2. Structural vibration levels may be higher at some frequencies than other MR Systems, which may increase acoustic levels. Refer to 2.5 Structure-borne Vibration Control Specications on page 22.

3. The VibroAcoustic damping kit must be surface mounted (if the oor is recessed, it must be lled in and level).

4. Ensure the existing Magnet Room size meets the minimum room size requirement and there is enough space left for service at both sides of the magnet. Refer to MR Suite Minimum Room Size

Requirements on page 17.

5. RF vendor responsibilities:

a. The old dock anchor cannot be reused. It must be removed and the hole lled in. The new

anchor is reset after the magnet is installed. For upgrades that reuse the existing magnet, contact the PMI for further details about the potential reuse of the old dock anchor.

b. Two penetration panel openings are required and must meet the requirements in: RF Shielded

Room Requirements, 5850260.

c. RF shield attenuation must comply with: RF Shielded Room Requirements, 5850260

6. Cryogen vent may need to be relocated to align with the Magnet Cryogen Vent opening. The cryogen vent must meet all cryogen venting requirements (see Magnet Room Venting Requirements,

5850263).

If the ceiling height is between 2500 mm (98.5 in) and 2667 mm (105 in), the exible main lead extension for low ceiling height (2.5M Low Ceiling Kit-Passive, M7000GM) is required for ramping the magnet. Contact the GE PMI and GE Service Field Engineer for further evaluation.

4. The minimum service area shown must be kept clear of permanent or installed cabinetry, the MRU, the penetration closet, millwork, shelving, coil storage xtures, furniture, and so on.

5. The ceiling service area should be kept clear of overhead items, including sots, HVAC, plumbing components, and brackets. Permanent or installed objects in this area may prevent or delay magnet service or operation.

2.4 MR System Seismic Requirements

Contact the Project Manager of Installation with any questions.

1. The customer is responsible for seismic anchoring of GE components.

2. Center of gravity, weight, physical dimensions, and attachment points are provided for seismic calculations. Refer to the specications or illustrations for each component (see Magnet

Preinstallation Manual 2.5 Structure-borne Vibration Control Specications

2.5 Structure-borne Vibration Control Specications

Structure-borne acoustic issues tend to occur at MR installations above the ground oor of the facility. Two options to mitigate structure-borne acoustic transmission are:

1. GE Healthcare provides a VibroAcoustic Damping kit (which must be surface mounted). Contact the GE Healthcare Project Manager of Installation for information.

2. The customer may design and implement a custom solution in addition to the VibroAcoustic Damping kit. See Figure 2-6 Vibration Transmitted through VibroAcoustic Mat on page 22 for the plot of spectral vibration transmitted through the VibroAcoustic mat into the oor. If required, the customer should consult an acoustic engineer for a solution to further attenuate this transmitted vibration).

NOTE

The amount of vibration attenuation provided by the VibroAcoustic Damping kit will be site dependent.

1. Illustrations above dene the potential vibration level that may pass into the customer site. Figure 2-6 Vibration Transmitted through VibroAcoustic Mat on page 22 is the high frequency audible vibration. Figure 2-7 Low Frequency Magnet Floor Vibration (Vibration

Amplitude at Each Foot) on page 23 is low frequency vibration that may dynamically

displace the oor.

2. Vibration transfer may be the result of customer specic building construction as low levels of vibration transmit into the building through airborne and structure-borne paths. Customer MR clinicians recognize the vibration dened in the tables is typically short bursts of vibration repeated multiple times as the scan progresses.

3. The customer should consider the impact of this vibration for the evaluation and design solution.

2.6.1 Magnetic Fringe Field

The following illustrations show the static magnet isogauss plot lines for the magnet. This information must be used to evaluate potential site interaction of GE Healthcare equipment with other non-GE Healthcare equipment, interaction with ferrous materials on the site, and to locate personnel and equipment within the site.

The 0.5 mT (5G) line can expand to 4.5 m (14.76 ft.) axially and 3.5 m (11.48 ft.) radially for up to 1 second in the rare event of a quench.

The isogauss plots show an idealized magnetic eld relative to magnet isocenter. The actual eld strength can be aected by any of the following:

• Magnetic shielding

• Earth's magnetic eld

• Other magnetic elds

• Stationary or moving metal

2.6.2 Interference from Changing Magnetic Fields

Metal objects moving within the magnet sensitivity lines can produce a eld disturbance during clinical imaging. If the metal object is moving it will produce a uctuating dipole type of eld which causes image artifacts. As an example, a car driven inside the moving metal line will act as a dipole and produce a time varying eld which changes the magnet's main eld during the scanning. The same vehicle may park within the moving metal line and remain parked during clinical scanning without impact to the main

eld.

Notes:

1. Radial distances are magnet X and Y axis. Axial distances are magnet Z axis.

2. For PM magnet: EXAMPLE: For moving metal requirements of objects > 181.44 kg (400 lb.) category, you can use the time history of

the occurrence to determine what Tesla (Gauss) level to use.

a. If the site has elevators or counter weights near the magnet and the elevator can stop on the oors for longer

than 20 seconds (which is usually the case), the peak-to-peak reading (Z-axis disturbance) must be less than 618 nanotesla (6.18 milligauss).

b. If the site has a subway nearby and the eld disturbance is less than 2 seconds, the peak-to-peak Tesla (Gauss)

reading (Z-axis disturbance) must be less than 618 nanotesla (6.18 milligauss).

c. Use 618 nanotesla (6.18 milligauss) peak-to-peak.

2.6.3 Electrical Current

1. Electrical current in high voltage power lines, transformers, motors, or generators near the magnet may aect magnetic eld homogeneity.

2. Magnetic eld interference at 50 or 60 Hz must not exceed 4 μT (40 mG) RMS at the magnet location (see Figure 2-13 Magnet Allowable Milligauss vs. Line Frequency for AC

Equipment on page 31).

3. The following equation can be used as a general guide in determining allowable current in feeder lines at a given distance from the magnet isocenter:

For 1.5T Magnet: I= (20X2)/S

b. I = Maximum allowable RMS single phase current (in amps) or maximum allowable RMS line

current (in amps) in three phase feeder lines

c. S = Separation (in meters) between single phase conductors or greatest separation between

three phase conductors

d. X = Minimum distance (in meters) from the feeder lines to isocenter of the magnet

2.9.3 Emergency Backup Facility Coolant Requirements

The customer must balance the cost of cryogens and local controls with the cost of emergency backup facility coolant. There are two options for emergency backup, either total ICC backup or Cryocooler Compressor backup.

The facility may provide an optional emergency backup coolant supply in one of the following

congurations:

Customer provided temporary backup water cooling is allowed for the Shield/Cryo Cooler Compressor Cabinet if chiller or ICC were to experience a fault and stop operating. The backup compressor cooling design can utilize open loop city water only as temporary backup during loss of the closed loop water from the LCS18 or ICC. Long term use of open loop cooling systems will not allow a chemical equilibrium establishment and eventually contribute to failure.

NOTE

It is recommended to discharge remaining coolant in the compressor before switching back to the normal cooling. Dispose of coolant in accordance with local regulations.

1. Total ICC backup:

a. The facility is responsible for the connection of all hoses of a backup system.

b. Coolant must meet all other ICC coolant requirements listed in 2.9.1 Integrated Cooling Cabinet

(ICC) Coolant Requirements-Type B Conguration on page 37.

2. Cryocooler Compressor backup only:

Backup coolant may be routed to the ICC backup water port for the Cryocooler compressor at the location indicated in Figure 2-16 MR System Water Cooling Block Diagram on page 39 with the following requirements:

3 Magnet Room

3.1 Magnet Room Introduction

The Magnet Room is best understood as a series of layers, or “rooms within a room.” Each of these rooms has a specic function and associated requirements. All requirements in this chapter must be followed to ensure safe and correct operation of the MR System.

1. The Magnetic shielded room contains the MR Magnet fringe eld within a conned space. A site survey is required to determine magnet shield requirements (not all sites require magnetic shielding). Because of the added cost of magnetic shielding, room location should be carefully considered.

2. The Acoustic room is a layer used to help attenuate the noise produced during a scan. An acoustic engineer is strongly recommended to assess the environment.

3. The RF shielded room is critical to the correct MR System operation. RF shielding prevents interaction of external RF radiation with MR System operation and it also prevents MR System RF radiation from interfering with external systems, such as aircraft control. Special care must be used when installing all xtures penetrating the RF shield (for example, vents, electrical conduit, penetration panels) to ensure the integrity of the RF shield is maintained. Refer to RF Shielded Room Requirements, 5850260.

4. The Finished room includes the wall coverings, ceiling tile, ceiling grid, other xtures, Magnet (MAG) and Patient Table (PT). When planning the nished room, ensure the following:

a. All building codes are met (such as maintaining egress routes).

b. Items which may generate or create RF interference (including orescence lighting) are not

allowed for installation within the Magnet Room.

c. Customer is responsible for the selection and installation of all locally required safety devices

(for example, smoke detectors, oxygen monitors, and so on).

d. Smoke detectors should be located outside of the Magnet Room (for example, within the

return air duct) whenever possible. If code does not allow this, use only simple two wire non-addressable smoke detectors in the Magnet Room.

e. Ferrous or metallic items which could become projectiles when the magnet is installed

(including wall coverings, ceiling tile, ceiling grid, or other xtures) are not used or are correctly secured.

Preinstallation Manual

3.2 Magnet Room Structural Requirements

This section lists the structural requirements that must be considered when performing site evaluation and planning of the Magnet Room.

3.2.1 Overview

1. When preparing a building plan or evaluating a potential site for an MR System, take care to ensure the MR suite will not interact with the surrounding environment (that is, magnetic, acoustic, environmental steel, and vibration).

2. The customer is responsible for vibration testing required to verify suitability of a proposed site. All test results and any questions regarding testing, results, or analysis must be forwarded to the GE Healthcare Project Manager of Installation (PMI).

3.2.2 Environmental Steel Limits

A static magnetic eld extends in a three-dimensional space around the magnet isocenter. Environmental steel within the static magnetic eld aects the uniformity (or homogeneity) of the eld. Field uniformity is critical to both image quality and chemical shift analysis (spectroscopy). An analysis of the environmental steel is required within a 3 m (9.84 ft.) spherical radius of the magnet isocenter. Environmental steel includes pipes, beams, concrete rebar, or any other structural steel in the oors, walls, or ceiling.

The following oor items must be limited per Table 3-1 Steel Mass Limits to Magnet Isocenter (3 x 3 m

(10 x 10 ft.) Area Under Magnet) on page 59.

1. Non-movable steel construction material such as rebar and metal decking

2. Existing or proposed RF/magnetic shielding or shim plates

3. Table 3-1 Steel Mass Limits to Magnet Isocenter (3 x 3 m (10 x 10 ft.) Area Under

Magnet) on page 59 denes the limits of use as a guideline to help the customer understand

allowable amounts of ferrous rebar, steel decking, or other components as they design the MR suite and Magnet Room oor structure.

4. The customer must provide detail dening ferrous material below the magnet to the Project Manager so the GE Healthcare MR Siting and Shielding (MRSS) team can review for compliance.

3.2.3 Vibration Requirements

Excessive vibration can aect 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, and so on) and transient vibrations (trac, pedestrians, door slamming, and so on) must be assessed (see 3.2.3 Vibration Requirements on page 59). Specic requirements for vibration mitigation, include:

1. The Magnet (MAG) cannot be directly isolated from vibration. Any vibration issue must be resolved at the source.

Distance Below Top Surface Of Floor mm (in.)

2. MR Suite HVAC must have vibration isolation.

3. A vibration analysis must be performed at the proposed site with the results (and any mitigation) forwarded to the GE Healthcare Project Manager of Installation (PMI). See the 8.2 MR Site Vibration

Test Guidelines on page 117.

4. A transient vibration test must only be performed after a steady-state test has been performed and all steady-state sources of vibration have been mitigated.

5. Transient vibration levels above the specied limits in the 8.2 MR Site Vibration Test

Guidelines on page 117 must be given to the PMI for review.

6. Any transient vibration that causes vibration to exceed the steady-state level must be mitigated.

7. The vibration test consultant must account for non-mechanically induced signals such as test equipment instabilities, thermal drift or RF interference.

3.3 Magnetic Shielded Room Requirements

Magnetic shielding prevents interaction between the magnet and nearby sensitive devices. Because of the added cost of magnetic shielding, room location should be carefully considered. All sites, including upgrade sites, must be evaluated for magnetic shielding requirements. Existing magnetic shielding at an upgrade site may not be sucient for the new system. Contact the GE Healthcare Project Manager of Installation (PMI) to request a site evaluation.

See MR Suite Magnetic Field Specications on page 24 for detailed magnetic proximity limit information.

1. The GE Healthcare Project Manager of Installation (PMI) works with the customer to coordinate the magnetic shielding site evaluation.

2. The customer is responsible for installation of all magnetic shielding.

3. If rear wall magnetic shield or steel RF wall is closer than 2500mm (98.4 in.) from isocenter, it should be veried by GEHC PMI.

3.4 Integrated System Cabinet (ISC) and Penetration Panel (PP) Wall Opening Requirements

The Penetration Panel must be covered on both sides and ISC must be covered on the magnet room side for safety. If GE-supplied adjustable covers are not used, the customer must furnish covers or enclosures with key or tool required for opening to limit access to the panel. The mounting and clearance dimensions for the Penetration Panel and the ISC are shown in this section.

ISC

The ISC back Cover depth is adjustable from 150 mm (5.9 in.) to 250 mm (9.8 in.).

The Penetration Panel Covers depth is adjustable from 300 mm (11.8 in.) to 400 mm (15.75 in.).

The Mesh Shield is adjustable from 100 mm (3.9 in.) to 110 mm (4.3 in.).

NOTE

When cutting the duct or pit for cable routing, make sure the ISC Cover can cover the cuto for the cable.

It is recommended to extend the Mesh Shield in between 100 mm (3.9 in.) and 110 mm (4.3 in.). However, the Mesh Shield can be extended to 180 mm (7.1 in.) without any slack. In case there is any reason that the ISC cannot be located closely enough to the RF Shield, it is local site engineer's responsibility to extend the Mesh Shield more than 110 mm (4.3 in.). Consider oor level under the ISC when extending the Mesh Shield more than 110 mm (4.3 in.).

Preinstallation Manual 3.5 Finished Room Requirements

3.5 Finished Room Requirements

3.5.1 Ferrous Materials in the Magnet Room

1. Non-ferrous (non-metallic) materials or components should be used in the Magnet Room.

2. Ferrous components or material in the Magnet Room that could be removed for servicing, cleaning, or replacement must be secured to prevent the ferrous material from becoming a projectile (ferrous components or material must also be identied as ferrous to prevent untrained personnel from working on the ferrous material while the magnet is energized).

3.5.2 Walls

Refer to Acoustic Room Details, 5850262. Hard, bare wall surfaces may create a harsh Magnet Room acoustic environment due to reection of sound waves. Finished walls with acoustic properties can reduce reected noise.

1. GE Healthcare recommends nished walls to protect the RF shielding.

2. Walls and any millwork, cabinets, storage areas, acoustic coverings, and so on, must remain outside the minimum service area.

3. A metallic electrical conduit inside walls and ceilings may be used. Conduit for receptacles must be metallic.

3.5.3 Magnet Preinstallation Markings

For correct cryogen venting, the magnet vent adaptor must align correctly with the ceiling vent when the magnet is installed.

1. The magnet isocenter position must be clearly marked, and the marking must be identiable throughout construction.

NOTE

If there is no ceiling grid in the room, we recommend to also mark the magnet isocenter location on the ceiling. This can serve as a reference for positioning a new vent pipe, or can be used to reproduce the oor markings if they become lost during construction.

Refer to Magnet Room Venting Requirements, 5850263 for the location of the magnet vent.

5538858-1EN Revision 4 SIGNA™ Prime 67/126

Preinstallation Manual

2. If no ceiling vent pipe exists prior to construction, the location of the magnet isocenter and magnet z-axis orientation must be marked on the Magnet Room oor as shown below.

Figure 3-9 Marking Magnet Isocenter (in a Room Without a Vent Pipe)

3.5 Finished Room Requirements

Figure 3-10 Marking the Magnet Isocenter and the Z-Axis Orientation on the Floor

3. If a ceiling vent pipe already exists at the start of construction, the magnet isocenter marking must be correctly aligned relative to the position of the vent pipe. Refer to Magnet Room Venting Requirements, 5850263, for vent location.

NOTE

We recommend:

• Marking the center of the vent pipe.

• Using a cross line laser or other accurate method to transcribe it to the oor directly

below.

5538858-1EN Revision 4 SIGNA™ Prime 68/126

Preinstallation Manual 3.5 Finished Room Requirements

• Marking the magnet isocenter relative to the vent pipe marking on the oor. The positioning template (5810898 or 5810898-2 ) can be used as a marking aid.

2. Threshold height must not exceed 15 mm (0.6 in.) on both sides of the door with a maximum 10-degree threshold inclination.

3. IEC requires the patient, while in the bore, be in full view of the operator.

NOTE

• GE Healthcare recommends using a window, although other means (for example, camera and video display) may be used as long as all IEC requirements are met.

• The recommended dimensions for the patient viewing windows are 1219 mm wide x 762 mm high (48 in. wide x 30 in. high).

• The recommended distance from the bottom edge of the patient viewing window to the nished oor is 1067 mm (42 in.).

4. The magnet delivery requires an opening into the room to allow access for the magnet delivery, rigging, and personnel access.

3.5.5 Finished Ceiling

1. The customer is responsible for the nished ceiling.

2. The nished ceiling grid must be non-ferrous.

3. Ceiling preparation should be completed prior to magnet delivery.

3.5.6 Magnet Room Floors

1. The nished oor must support the weight of all components throughout operation and service life. This includes the magnet, patient table, and gradient coil replacement cart.

NOTE

For gradient coil replacement, eld engineers remove the patient table from the Magnet Room before they move the gradient coil replacement cart into the Magnet Room.

2. The nished oor must be water resistant to protect the suboor and shielding from water damage.
