Diagnostic radiological apparatus

摘要

The invention relates to a computer tomograph with alternating rotation and lateral displacement of the X-ray beam (1a) transirradiating the patient. For the purpose of lateral movement of the X-ray beam (1a) for a specific angular setting of the turntable supporting the X-ray tube (1) and the radiation detector, the X-ray tube (1) is constructed as a rotating-anode tube whose anode track (13) is situated in the direction of the axis of rotation (14) of the anode such that the distance focus(11) -cathode (9) varies during the rotation of the anode. <IMAGE>
