Abstract:
1. A method for registering at least two volume data records of the intestine which were recorded in two different positions of a patient using a tomographic imaging method, the method comprising: generating a registration matrix which assigns to each voxel illustrating the intestine, in one volume data record of the at least two volume data records, a corresponding voxel in another volume data record of the at least two volume data records intended to represent a same location in the intestine, the generating including performing an approximate registration in which an intestinal profile is respectively determined for the at least two volume data records, registering the at least two volume data records on the basis of similarities between the two intestinal profiles, and subsequently performing a detailed registration on the at least two volume data records in which the approximate registration is refined on the basis of local anatomical features in the intestine so as to generate the registration matrix for the at least two volume data records.
