ABSTRACT:
An x-ray generator has a beam guidance system including an air coil and a toroidal solenoid coil, a ring anode surrounding the patient to be examined and arranged axially offset relative to the beam guidance, and individually driveable electron-optical components couple the electrons, which orbit on a circular specified path in the magnetic dipole field of the air coil, out of that path, deflect them in the axial direction, and focus them onto a segment of the ring anode allocated to the respectively activated out-coupling element.
