发明名称 X-ray computed tomography apparatus with light beam-controlled x-ray source
摘要 An x-ray computed tomography apparatus has a stationary x-ray detector that at least partially surrounds the examination volume in one plane and a stationary device for generation of x-ray radiation. The device for generation of x-ray radiation is composed of an x-ray source that extends annularly around the examination volume over an angle of at least 180° as well as one or more light scanning units with which an x-ray focus moving along the x-ray source can be generated on the x-ray target by scanning of the x-ray source with a light beam, from which x-ray target an x-ray beam is directed through the examination volume onto respective, momentarily opposite detector elements of the stationary x-ray detector. The computed tomography apparatus has one or more light scanning units are arranged and fashioned outside of a central ring axis of the x-ray source such that only an angle range <360° is respectively scanned with each light scanning unit without crossing the ring axis.
