Abstract
A gantry (A) has a bore defining a first 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. An angiographic device (D) is positioned remote from the gantry along a longitudinal axis (25) for generating and displaying angiographic image representations on a display monitor (46). A second examination region is defined along the longitudinal axis (25) between a second x-ray source (36) and an image intensifier tube (38). A second processor (44) reconstructs the angiographic projection image representations from signals generated by the image intensifier tube (38). A C-arm (30) can be suspended from an overhead track (50) for supporting the second x-ray source (36) and the image intensifier tube (38). A common patient support (24-28) extends along the longitudinal axis between the gantry and the angiographic device for positioning a patient within the first an…
