CUSTOMER RESPONSIBILITIES

• It is the responsibility of the customer to prepare the site in accordance with the specifications stated in the final study. A detailed site readiness checklist is provided by GE. It is the responsibility of the customer to ensure all requirements are fulfilled and that the site conforms to all specifications defined in the checklist and final study. The GE Project Manager of Installation (PMI) will work in cooperation with the customer to follow up and ensure that actions in the checklist are complete, and if necessary, will aid in the rescheduling of the delivery and installation date.
• Prior to installation, a structrual engineer of record must ensure that the floor and ceiling is designed in such a way that the loads of the installed system can be securely borne and transferred. The layout of additional structural elements, dimensioning and the selection of appropriate installation methods are the sole responsibility of the structural engineer. Execution of load bearing structures supporting equipment on the ceiling, floor or walls are the customer’s responsibility.

RADIO-PROTECTION

• Suitable radiological protection must be determined by a qualified radiological physicist in conformation with local regulations. GE does not take responsibility for the specification or provision of radio-protection.

ENVIRONMENT

ALTITUDE

• Operating altitude: from -150 m [-492 ft] to 3000 m [9,843 ft].

MAGNETIC FIELD SPECIFICATIONS

• In order to avoid interference on the system, the static field limits from the surrounding environment must be less than 1 Gauss in both the scan and the operator rooms.
• The ambient static magnetic field in the system location must be less than 1 Gauss.
• The ambient AC magnetic fields must be below 0.01 Gauss peak.
• The system must be installed in an x-ray protected room providing an attenuation of at least 12 db for radio disturbances from 30 MHz to 1 GHz.

MAXIMUM GANTRY AUDIBLE NOISE LEVEL

• The system creates acoustic noise. In compliance with IEC 601-1-1 standard the measured noise (at 1 m [3.3 ft] distance away from the system) is less than 70 db. It is recommended that the wall and ceiling surface is of a sound dampening material to avoid noise reverberation and amplification.
• Take into account that the system includes an intercom communication system connecting the Operator room and the Scan room, to enable the operator to give the patient instructions during the examination.

VIBRATION SPECIFICATIONS

• The system components are sensitive to vibration in the frequency range of 0.5 to 20 Hz, depending on the amplitude of the vibration. It is the customer’s responsibility to contract a vibration consultant or qualified engineer to verify that these specifications are met and implement an appropriate solution.
• To minimize vibrations, the system must be installed on a solid floor, as far as possible from vibration sources (parking lots, roadways, subways, heliports, trains, hallways, elevators, hospital power plants… etc).

CUSTOMER SITE READINESS REQUIREMENTS

• Any deviation from these drawings must be communicated in writing to and reviewed by your local GE healthcare installation project manager prior to making changes.
• Make arrangements for any rigging, special handling, or facility modifications that must be made to deliver the equipment to the installation site. If desired, your local GE healthcare installation project manager can supply a reference list of rigging contractors.
• New construction requires the following;
  1. Secure area for equipment,
  2. Power for drills and other test equipment,
  3. Capability for image analysis,
  4. Restrooms.
• Provide for refuse removal and disposal (e.g. crates, cartons, packing)
• For CT, MR, PET/CT, and SPECT systems it is required to minimize vibrations within the scan room. It is the customer’s responsibility to contract a vibration consultant/engineer to implement site design modifications to meet the GE vibration specification. Refer to the system preinstallation manual for vibration specifications.

RADIOACTIVE ISOTOPES

USING RADIOACTIVE ISOTOPES

Since the system involves the use of radioactive isotopes, compliance with Nuclear Regulatory Commission regulations, or similar regulatory requirements (depending on the country), must be adhered to and all permissions obtained well in advance. It is recommended that regulatory compliance is arranged early in the site planning process. It is essential that all preparations are completed so that required source materials can be obtained prior to installation, including calibration sources. Take into consideration that these sources may have fairly long delivery lead times, yet may also have a short half life, so that it may not be advisable to store them over long periods of time.

SHIELDING REQUIREMENTS:
Radiation shielding regulations differ from one country or state to another. It is the customer’s responsibility to ensure that radiation protection and shielding comply with such regulations and requirements during site preparation and system installation and operation. The system produces x-ray radiation and involves the use and storage of radionuclides. Appropriate barriers such as walls, lead-shielded glass, lead shields, etc. can be installed to protect staff from unnecessary exposure to radiation. Patients become significant sources of radioactivity; therefore consideration should be given to maximize the distance between the patient and operator during the uptake and acquisition phases of scan procedures. Scatter-room shielding requirements must be reviewed by a qualified radiological health physicist taking into consideration:

• Scatter radiation levels within the scan room
• Equipment placement
• Weekly projected workloads (#patient/day technique (kvp*ma))
• Materials used for construction of walls, floors, ceiling, doors, and windows
• Access to areas surrounding the Scan Room
• Equipment in areas surrounding the Scan Room (for example: film developer, film storage)
