    • The present invention relates to an X-ray system and method for generating 3D image data. The X-ray system comprises 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 the X-ray tube assembly can be moved into relative positions relative to the radiation detector. Projection images recorded in the relative positions can be processed together with the coordinates of the relative positions using an iterative reconstruction technique or other image processing methods so as to obtain 3D X-ray images. The X-ray tube assembly is attached to a motor-driven movable stand arm and can be displaced using a control unit. The stand base of the movable stand can be positioned in a spatially fixed manner, so that it has a defined fixed position relative to the radiation detector.
    • 本发明涉及一种用于产生3D图像数据的X射线系统和方法。 X射线系统包括辐射检测器,可移动X射线管组件和控制单元,其中在系统的工作状态下,辐射探测器以空间固定的方式可拆卸地定位,并且X射线管组件可以 移动到相对于辐射检测器的相对位置。 可以使用迭代重建技术或其他图像处理方法,在相对位置记录的投影图像与相对位置的坐标一起被处理,以获得3D X射线图像。 X射线管组件连接到电动可移动支架臂上,并可使用控制单元进行移位。 可移动支架的底座可以以空间固定的方式定位,使得其相对于辐射检测器具有限定的固定位置。
