摘要： 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.

摘要： A method is disclosed for identification of a contrasted blood vessel in digital 3D image data, the method using a generic region-growing algorithm with several steps, for which among other things seed points are searched for and, in dependence on a current threshold value, are assigned to corresponding seed point sets. The number of seed points which are associated during a specific section of the method to the same seed point set with the threshold value is recorded and a leakage signal is produced if the number exceeds a maximum value. When the leakage signal occurs, those seed points which have been associated with the threshold value during that section are not stored as vessel voxels, the method is terminated at the location of the leakage and the remaining method is continued.

摘要： A method and an apparatus are disclosed for registering at least three different image data records for an object. In at least one embodiment, the method involves first of all determining for each image data record the anatomical region which is covered by the image data record. Next, degrees of overlap in these anatomical regions are calculated. These degrees of overlap are taken as a basis for determining the image data record as a master image data record which, in total, has a maximum overlap with the other image data records, ignoring degrees of overlap which are below a prescribable lower threshold. The other image data records are then registered merely with the master image data record. Thus, they are automatically also indirectly registered with one another. At least one embodiment of the present method and the associated apparatus reduce the waiting time for the user who wishes to visualize a plurality of the image data records simultaneously next to one another or superimposed on one another.
