Abstract
A method is disclosed for the segmented representation of vessel-like structures of an object under examination, on the basis of tomographic data, wherein a three-dimensional tomographic volume data record of the object under examination is generated and a segmentation is carried out which enhances the vessel-like structures in the representation of the tomographic data. According to an embodiment of the invention, for each voxel, the probability with which the voxel is located in a vessel structure is determined from the environmental data of the voxel with the aid of a vessel-specific filter of a spatial dimension which corresponds to the tomographic volume data record, on the basis of Gaussian functions, and these determined probabilities are additionally used as criterion for the presence of a vessel in the segmentation process for the representation of vessel structures. An embodiment of the invention also relates to a tomography system, with a device for scanning an object under examination, preferably a patient, and at least one computer system for editing tomographic image data records containing a memory for storing program code and a processor system for executing the programs, wherein program code is stored which executes the method steps of an embodiment of the method.
