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