Abstract: A computer Tomograph having a housing with an aperture (2) for the patient in which computer-controlled scanning devices are arranged to generate computer tomograms, and into which a motor-driven, and also computer-controlled, patient's couch can be inserted from the front of the housing (1). The patient's couch also acts as an operating table, such that as little information as possible is lost in the treatment of the patient between diagnosis and the action on, or treatment of, the patient. The action or treatment can thereby be as close as possible to the diagnosis both in time and place. At the front of the housing (1), there is a plurality of information displays connected to the computer, especially in the form of display screens. In front of the housing (1) there is an operation and treatment area for the patient, to which further diagnostic and/or operative and/or therapeutic auxiliaries are allocated.
