GRADUAL MOVEMENTS OF THE FOCAL POINT OF X-RAY RADIATION FOR A GRADUAL TRANSITION BETWEEN MONOSCOPIC AND STEREOSCOPIC VIEWING

摘要

1. An x-ray tube (30) for monoscopic and stereoscopic viewing, comprising a cathode device (32); an anode (34) and control means; wherein the cathode device and anode provide for generating an electron beam (36) from the cathode device in the direction of the target region of the anode for generating x-ray radiation (38) by electrons incident on the target region; moreover, control means are provided to control the electron beam so that the electrons hit the anode at different target points; moreover, the control means is configured to provide a gradual change in the direction of incidence of electrons for a stepless transition between monoscopic and stereoscopic viewing; moreover, during monoscopic viewing, x-ray radiation is generated from a single focal point position, and when stereoscopic viewing, x-ray radiation is generated from two focal point positions spaced apart distance from each other in the first stereo direction (40) transverse to direction (42) view but; Moreover, the control means is configured to provide a gradual change of at least one focal stereo point also in the second stereo direction (46), which is transverse to the first stereo direction and the transverse direction of viewing. 2. The x-ray tube according to claim 1, wherein the control means is configured to provide a gradual change so that when stereoscopic viewing, the connecting line between the first focal point and the second focal point is located on a common plane with the viewing direction.
