Title: X=ray tube with variable sized X=ray focal spot and focus switching
Inventor: HELL ERICH
IPC: H01J35/30
Filed: 1998-05-06
Abstract: The X-ray tube has an omnidirectional emitter and a rotating casing with a cathode and an anode, which is surrounded by a magnet system that generates a dipole field and an superimposed quadrupole field to deflect and focus the X-ray beam on the edge of the anode. The tube also has an arrangement to change the size of the focal spot. To increase the size of the focal spot, the quadrupole field is altered, so that the electron beam is widened transversely to the anode radius to the width of the desired focal spot, by shortening the radial length of the beam.  The deflecting dipole field superimposes a sweep voltage, to periodically displace the focal spot in the radial direction of an overall distance, which corresponds to the product of the desired focal sport diameter and the projection ratio of the inclined anode edge in the radiation direction of the X-ray beam.
