X-RAY TUBE WITH A COMBINED X- AND Y- FOCAL SPOT DEFLECTION METHOD |
摘要 |
An X-ray tube is provided adapted to generate X-ray beams, comprising a first and a second deflection device mounted external or internal to the X-ray tube between a cathode and an anode in a diagonal manner for focal spot deflection in a combined x- and y-direction. The first and second deflection devices are triggered alternately such that only one deflection device is activated at a time. The first and second deflection devices may be triggered according to a predetermined switching sequence, e.g. producing a predetermined deflection pattern of the focal spot. Thereby, an improved x- and z-flying focal spot methodology is provided.
