The stationary gantry which the diagnosis image pickup null suffering inspection body reception aperture which includes the source of transmitted radiation and the source

摘要

Diagnostic imaging system includes a rotating gantry which defines a subject receiving aperture. 2-dimensional flat panel X-ray detector and corresponding sources rotatable high energy penetrating radiation is spaced apart a subject receiving aperture. Nuclear detector heads plurality is movably mounted at the rotating gantry to detect radiation emitted by the radiopharmaceutical is injected into the subject. Nuclear detector heads in the system includes a variable radiation shield which is disposed adjacent, respectively, the radiation receiving surface of the detector head. Diagnostic imaging system may operate in a volume imaging mode or fluoroscopic / radiographic mode isocenter X-ray beam hits the center of the detector head.
