ABSTRACT:
A peripheral cooling duct (36) is mounted on a removable front door panel (26) of a CT scanner (10). A pressure source (74) supplies ambient air at elevated pressure through air inlet means (70) defined by an inner wall (78) of the cooling duct. Concentric flanges (58, 60) extending inward toward the inner region (76) of the CT scanner define a slit-like circular nozzle opening (56). Air is directed from the cooling duct through the nozzle opening across radiation detectors (20) for cooling the detectors and other features of the CT scanner during scanner operation.
