Scan Room Lighting; Operator Room Lighting (If Applicable) - GE Discovery NM/CT 670 Instructions Manual

Electrical Requirements

5.7.1 Scan Room Lighting

The lighting should be planned so there is sufficient light for:
Scan preparation

Scan setup

Patient unloading

Working light for service and maintenance activities

The lighting should be designed so that it can be dimmed or otherwise changed in order to minimize
discomfort for patients lying supine for extended periods on the patient table with the ceiling in view.
NOTE
Scan room lighting above the gantries and patient table area should consist of fluorescent lights only (no direct

sunlight or direct bright light from filament light bulbs).
During system servicing in the scan room, a relatively bright light is required in the area behind and around the

gantry.

5.7.2 Operator Room Lighting (if applicable)

The lighting should be planned taking into account that operators will be working with computer
monitors and reading digital images during much of the day. Reflections in monitors should be
avoided, and other ergonomic factors taken into account.
The operator room lighting must also take into account that relatively bright light is required while
servicing the CT console (NIO) and/or NM acquisition station.
