Abstract

A frame (A) of a diagnostic imaging device such as a CT scanner or an MRI device has a bore defining a patient examination region (12). A first x-ray source (B) is mounted to a frame (C) for rotation around the examination region (12). An arc of first radiation detectors (14) detects x-rays which have traversed the examination region. A first image reconstruction processor (18) reconstructs a tomographic image representation from signals generated by the first radiation detectors. A fluoroscopy device (D) is mechanically coupled to the diagnostic scanner for generating and displaying at least substantially real-time fluoroscopic projection image representations on a display monitor (60). A second x-ray source (32) transmits x-rays to an amorphous silicon flat panel radiation detector (36). A second image reconstruction processor (58) reconstructs the fluoroscopic projection image representations from signals generated by the flat panel radiation detector (36). A C-arm (30) supports the second x-ray source (32) and the flat panel radiation detector (36) in a plane offset from a plane of the C-arm. A movable mounting structure (E) is mechanically connected with the gantry (A) and the C-arm (30) to move the C-arm between a stored position and an operating position adjacent the bore.
