GE Optima CT520 CT Scanner: Installation and Site Readiness

General Specifications and Disclaimer

GE is not responsible for the installation of developers and associated equipment, lighting, cassette trays, and protective screens not mentioned in the order. The final study contains recommendations for equipment location, electrical wiring, and room arrangements. Room dimensions may originate from previous layouts and may not be accurate. GE cannot take responsibility for errors due to lack of information. All work must comply with building regulations and safety standards. These drawings are not for actual construction purposes.

Customer Responsibilities

The customer must prepare the site according to the final study specifications. A detailed site readiness checklist is provided. The GE Project Manager of Installation (PMI) will assist in ensuring all requirements are met. A structural engineer must verify that the floor and ceiling can support the system's loads. The customer is responsible for the execution of load-bearing structures.

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.

Global Site Readiness Checklist

The checklist covers EHS site requirements, mechanical installation readiness, and calibration readiness. Key points include ensuring clear access routes, adequate facilities for GE employees, a safe work environment free from chemical hazards, and proper room dimensions, ceiling height, and floor levelness.

Environment

• Altitude: The system meets specifications at elevations from -150 m to 3000 m.
• Magnetic Field Specifications: Limit magnetic interference to guarantee imaging performance. Ambient static magnetic fields should be less than 1 Gauss, and AC magnetic fields less than 0.01 Gauss peak for the gantry. For the operator console, static magnetic fields should be less than 10 Gauss.
• Gantry Audible Noise Level: Maximum ambient noise level is less than 70 dBA at one meter from the gantry surface.
• Console Audible Noise Level: Maximum ambient noise level is less than or equal to 56 dBA at one meter from the console.

Customer Site Readiness Requirements

• Any deviations from drawings must be communicated to the GE healthcare installation project manager.
• Arrange for rigging, special handling, or facility modifications.
• For new construction, ensure a secure area for equipment, power for testing, image analysis capability, and restrooms.
• Provide for refuse removal and disposal.
• Minimize vibrations within the scan room by contracting a vibration consultant.

Equipment Layout

This section details the layout of the GE Optima CT520 system, including the exam room and control room. It provides a legend for GE-supplied and customer-supplied equipment and lists the heat output and weight for various components.

Radiation Protection Layout

The document includes a radiation protection layout with shielding requirements scaling based on parameters like kVp and mAs. It emphasizes engaging a qualified radiological health physicist to review specific shielding needs, considering scatter radiation, equipment placement, and building materials.

Radiation Scatter Diagrams

Diagrams illustrate radiation scatter patterns for both head and body phantoms, showing approximate radiation levels at various distances and angles.

Equipment Dimensions

Detailed dimensions are provided for the Gantry with Table, Power Distribution Unit (PDU), Aurora SWS Table, Open16 Console with Z8G4 Host PC, and Main Disconnect Panel. These include front, side, and top views with measurements in both millimeters and inches.

Delivery

Customer/contractor should provide an adjacent area for delivery and unloading. Ensure all doors, corridors, and ceiling heights accommodate equipment movement. Arrangements must be made for stopping and unloading. Dimensions and weights for gantry and lite table delivery are provided.

Structural Notes

All steel work and parts for supporting ceiling-mounted equipment are to be supplied by the customer or contractors. Methods of support should favor attachment to structural steel or through bolts in concrete. Wall-mounted units require customer-supplied supports. Ceiling-mounted fixtures should be flush or not extend more than 1/4" below the finished ceiling. Floor slabs must be level to 1/4" in 10'-0". Customers must provide for all penetrations and non-standard anchoring. The customer is responsible for performing floor or wall penetrations and ensuring no subsurface utilities interfere with the process.

Structural Layout and Details

Diagrams show gantry and table leveling pads, support backing, and anchoring/loading distribution to the floor. Floor requirements include specific anchor types, torque specifications, and finished floor levelness tolerances.

HVAC and Heat Dissipation

Temperature and humidity specifications are provided for both in-use and storage conditions for the exam and control rooms. Heat dissipation details for various components like the gantry, patient table, PDU, and console are listed in kW and BTU.

Electrical Notes and Requirements

All specified wires must be copper stranded and flexible. Wire sizes should be verified by local codes. Convenience outlets and general room illumination are not illustrated but should be considered. A special grounding system is recommended. Primary power connection must be made by the customer's electrical contractor with GE supervision. GEHC conducts power audits to verify power quality.

Connectivity Requirements

The system requires local and remote connectivity for digital support. This includes network information for local devices and a broadband connection for remote support (InSite™). Preferred connection methods include TLS over TCP Port 443 or IPsec VPN tunnels.

Power Distribution and Cable Management

The document details power requirements, including single-phase and three-phase power, maximum input power, and power factor. It outlines the power distribution system, including the Main Disconnect Panel (MDP) and Power Distribution Unit (PDU). Cable management guidelines and feeder tables are also provided.

Interconnections

Diagrams illustrate typical cable management within the floor and interconnections between various system components in the exam and control rooms, including distances for cable runs.
