A method is disclosed for establishing at least one change in a tubular tissue structure in a living being from a first time to a second time, which differs from the first, wherein the midline of the tubular tissue structure is respectively determined in a provided first volume data record, generated at the first time, of the tubular tissue structure in the living being, and in a provided second volume data record, generated at the second time, which differs from the first, of the tubular tissue structure. In at least one embodiment, at least one change in the minimum and/or the maximum diameter of the inner wall of the tubular tissue structure and/or at least one change in the minimum and/or the maximum diameter of the outer wall of the tubular tissue structure is established in order to establish the at least one change in the tubular tissue structure along the tubular tissue structure at mutually corresponding positions of the midlines of the tubular tissue structure in the first volume data record and the tubular tissue structure in the second volume data record. At least one embodiment of the invention also relates to a calculation unit for carrying out the method and to a data storage medium, which has a calculation program implementing the method. |
