Abstract
An X-ray radiator with a rotating bulb X-ray tube, with an allocated deflecting magnet system having at least one current-supplied coil for generating a magnetic deflecting field, has a circuit for tapping at least one reference signal representative of the high voltage existing at the X-ray tube. The coil current is adjusted by a control unit depending on this reference signal.
Claims13
An X-ray radiator comprising:
- a radiator housing;
- a rotary X-ray tube rotationally mounted in said radiator housing, said X-ray tube including a cathode, which emits an electron beam, and an anode, on which said electron beam is incident for producing X-rays;
- a magnet system disposed in said radiator housing which interacts with said electron beam to selectively deflect said electron beam from a straight line proceeding between said cathode and said anode, said magnet system including a coil in which a coil current flows;
- an electrical tap for obtaining a reference signal corresponding to a high voltage existing between said cathode and said anode;
- and
- a control unit, supplied with said reference signal, for adjusting said coil current dependent on said reference signal.
