9.3 Gantry Air Inlets

The operator must inspect both the left and right gantry air inlets to make sure they not being
blocked before operating the CT system and during operation. The system receives cooling air
through the air inlets. Blocking the air inlets leads to a reduction in air flow and potentially
overheating of the system. [The minimum distance to any object blocking the flow shall be 75
mm (3 inches).] Critical objects are jackets, robes, lab coats, bed sheets, pillow cases, covers or
blankets that can get sucked into the air inlet and provide an excellent blockage and seal for air
flow, despite initial proper spacing. Also paper sheets can get sucked into the air inlet and get
stuck in front of the filter. For proper inspection, the operator should be able to clearly see the
air filter through the opening of the air inlet.
