ABSTRACT:
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.
