摘要： The invention relates to a medical imaging system as well as a collision protection method for such a system. In this system the movement of a moveable part, e.g. a C-arm, is stopped or slowed down, if the part enters an individual protective zone enclosing the patient. This zone is calculated individually for each patient from the surface of the patient detected by an optical sensor.

摘要： The invention relates to a method for “truncation correction” in an x-ray system, i.e. a correction method during the reconstruction of projection images of an object recorded from different projection angles, if parts of the object do not lie in the field of view of each projection image. The surface of the object is thereby optically detected and used during the reconstruction of projection images to supplement the missing image data.
摘要翻译：本发明涉及一种在X射线系统中进行“截断校正”的方法，即在从不同投影角度记录的物体的投影图像的重建期间的校正方法，如果物体的部分不在视野内的每个投影图像。因此，在重建投影图像期间光学检测并使用对象的表面以补充丢失的图像数据。

摘要： A device and a method for the multispectral correction of radiation hardening in computer tomography with variable tube voltage is described. In particular, a water correction and a post-reconstructive hardening correction is disclosed. To perform the water correction, project image data is corrected, in that correction values are obtained from a previously determined correction table, by means of which a correction of the projection image data can be performed. By means of an image reconstruction, this produces a corrected volumetric image.

摘要： A method for operating a computed tomograph is provided, wherein an X-ray penetrates an object from different positions, a deposition of an individual dose is effected in at least one part of the object, and an image signal is generated in the detector by way of a transmitted intensity of the X-ray, wherein exposure-related parameters for the respective different positions are individually set such that with respect to a specific position, the share of the associated individual dose is raised if a raising of the individual dose in the specific position brings about a greater improvement in the image quality than in another position, or the share of the associated individual dose is lowered if a lowering of the individual dose in the specific position brings about a smaller deterioration in the image quality than in another position, in order to lower stochastic risks for mutations and uncontrolled cell growth.
