Patent ID: 8908938

Claim:
A method for providing a segmented volume data record for a virtual colonoscopy, the volume data record including image information relating to the intestines of a creature, the method comprising: emitting beams from an observer position in the intestines; labeling, by one or more processors, the intestines by using a first and a second contrast agent, voxels representing stool remains being labeled by the second contrast agent; segmenting, by the one or more processors, voxels representing intestinal tissue, the segmentation taking place in a volume data record recorded of the body region of the creature including the intestines, labeled by the first and the second contrast agent; and displaying, by the one or more processors, without digital subtraction of the stool remains labeled by the second contrast agent, at least sections of an intestinal wall of the intestines on the basis of the segmentation in the virtual colonoscopy, when the sections of the intestinal wall are, in the segmented volume data record, covered by stool remains labeled by the second contrast agent, the displaying including, reconstructing at least one view of an interior of the intestines using a surface-shaded display in the virtual colonoscopy based on the segmented volume data record, the reconstructing beginning from the observer position in the intestines and including, determining if the intestinal wall in the segmented volume data record is covered by stool remains labeled by the second contrast agent, illustrating at least one image voxel on the beams when a voxel value of an associated image voxel exceeds a voxel threshold assigned to the intestinal wall when the intestinal wall in the segmented volume data record is covered by stool remains labeled by the second contrast agent, and illustrating the at least one image voxel on the beams when the voxel value of the associated image voxel exceeds the voxel threshold assigned to the intestinal wall when the intestinal wall in the segmented volume data record is not covered by stool remains labeled by the second contrast agent.
