Claim Text:
1. An X-ray system for generating 3D image data, comprising: a radiation detector, a movable X-ray tube assembly and a control unit, wherein in a working state of the system the radiation detector is detachably positioned in a spatially fixed manner and defines a locally fixed base coordinate system, and the X-ray tube assembly is movable relative to the radiation detector into different relative positions so as to record X-ray projection images, wherein projection images recorded in the relative positions, combined with the coordinates of the relative positions, are processable using an iterative reconstruction technique or other image processing methods to obtain 3D X-ray images, and wherein the system comprises a movable stand having a motor-driven movable stand arm and a stand base, wherein the X-ray tube assembly is attached to the stand arm and is movable in at least four degrees of freedom, and the stand base comprises fastening devices for the spatially fixed positioning and, in the working state, is positioned in a spatially fixed manner such that it has a defined fixed position within the base coordinate system, and the stand arm is displaceable into the relative position by way of the control unit, wherein the stand base comprises one or more sensors for ensuring that a spatially fixed position of the stand base is maintained.
