摘要： A system for providing a simulated spatial live viewing of an object includes a cathode arrangement configured to generate an electron beam towards a target area of an anode, and a processor configured to control the electron beam to hit the anode at a moving focal spot that moves at least in a first moving direction transverse to a viewing direction. Thus, X-ray radiation is generated by the electron beam impinging on the moving focal spot. Further, the system includes a detector configured to detect X-ray radiation at least partially passing an object and to generate respective X-ray detection signals. The processor is further configured to generate monoscopic 2D images based on the detection signals, where the monoscopic 2D images relate to different view-points as defined by the moving focal spot. A display is configured to display the monoscopic 2D images are from the different view-points.

摘要： The present invention relates to monoscopic and stereoscopic X-ray viewing. In order to provide an improved fluent work flow for X-ray viewing with an improved visual perception of depth information, it is provided to generate an electron beam from a cathode arrangement towards a target area of an anode; to deflect the electron beam such that the electron beam hits the anode at different target spots (94a, 94b), wherein the variation is provided as gradual variation of an impinging direction of the electrons such that a stepless transition between monoscopic and stereoscopic viewing is provided. In the monoscopic viewing, X-ray radiation is generated from a single focal spot position, and wherein in the stereoscopic viewing, X-ray radiation is generated from two focal spot positions spaced apart from each other in a first stereo-direction transverse to a viewing direction (92). It is further provided to generate X-ray radiation by the electron beam impinging on the target area, wherein the X-ray radiation is provided with different focal spots for monoscopic and stereoscopic X-ray imaging. Still further it is provided to display or otherwise provide image data of the object with a gradual transition between monoscopic and stereoscopic viewing.

摘要： An X-ray tube includes a cathode, an anode, and a deflection device. The cathode and the anode generate an electron beam that is directed toward a target area of the anode to generate X-ray radiation through electrons of the electron beam impinging the target area. The deflection device controls the electron beam such that the electrons hit the anode at different focal spot positions. The deflection device provides gradual deflection for a stepless transition between monoscopic viewing and stereoscopic viewing. For monoscopic viewing, the X-ray radiation is generated from a single focal spot position. For stereoscopic viewing, the X-ray radiation is generated from two focal spot positions spaced apart in a first stereo-direction transverse to a viewing direction. The deflection device provides gradual deflection for a stereo focal spot position in a second stereo-direction, which is transverse to the first stereo-direction and the viewing direction.

摘要： An interventional X-ray system is proposed, the system including a multi X-ray source unit positioned below a patient table. This ‘multiblock’ may comprise several x-ray sources with focal spot positions distributed along the x-y (table) plane. The x-ray sources are operable in a switching scheme in which certain x-ray sources may be activated in parallel and also sequential switching between such groups is intended. The switching may be carried out so that several images with different projection angles can be acquired in parallel. In other words, an optimal multi-beam X-ray exposure is suggested, wherein fast switching in one dimension and simultaneous exposure in the 2nd dimension is applied.
