摘要： A method and an apparatus for virtual bowel cleaning are disclosed. A first CT volume data record of an area of the bowel of interest is produced, in which voxels relating to a bowel content are identified and are suitably modified in order to obtain a modified data record without visible bowel contents, which is then visualized. In at least one embodiment of the method, at least one further volume data record is produced of the area of interest, which was recorded by a CT scanner with a different spectral distribution than the first volume data record which was recorded by a CT scanner, with at least some of the voxels relating to the bowel content being identified on the basis of information about a local density and/or atomic number, which is obtained from data in the first and the further volume data record taking account of the different spectral distributions. In at least one embodiment, the method and the apparatus make it possible to increase the reliability of virtual bowel cleaning.

摘要： In a method for operation of an imaging medical apparatus, a recumbent board supporting an examination subject is positioned in the scan region of the medical-technical apparatus, an exposure of both a section of the recumbent board and of a part of the tissue of the examination subject to be examined in the scan region is generated, the acquired real position of the section of the recumbent board is compared with an expected position of the recumbent board by image evaluation of the exposure generated with the medical-technical apparatus, and the exposure generated with the medical-technical apparatus of the examined tissue is corrected using the expected-real comparison of the position of the recumbent board.
摘要翻译：在成像医疗装置的操作方法中，支撑检查对象的躺椅位于医疗技术装置的扫描区域中，躺卧板的一部分和组织的一部分的曝光产生在扫描区域中进行检查的检查对象，通过用医疗技术设备生成的曝光的图像评估将躺椅的部分的获得的实际位置与卧式板的预期位置进行比较，并且曝光使用所检查的组织的医疗技术装置产生的产生使用所述卧式板的位置的预期的 - 真正的比较来校正。
