Lighting is one of the most critical factors that must to be addressed in PACS reading room design. A PACS reading room should have limited extraneous ambient light comin from behind the workstation. Background lighting and glare issues can have a significant effect on the readability of the images on the workstations. Indirect lighting is critical to the room design, including desk lamps for reading paper reports. These simple design criteria become very complex, if not impossible, when mixing film-based reading systems (e.g., motorized X-ray view boxes with their banks of high-intensity bulbs) with PACS workstations in the same room. Obviously, ample electrical outlets and HVAC are also required
