Abstract:
1. A method 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, the method comprising: determining a midline of the tubular tissue structure in a provided first volume data record, generated at the first time, of the tubular tissue structure in the living being, and determining a midline of the tubular tissue structure in a provided second volume data record, generated at the second time, of said tubular tissue structure; respectively determining at least one of an inner wall of the tubular tissue structure and an outer wall of said tubular tissue structure in the first volume data record of the tubular tissue structure and in the second volume data record of said tubular tissue structure; registering the tubular tissue structure in the first volume data record and the tubular tissue structure in the second volume data record with respect to one another on the basis of their respective midlines; respectively establishing at least one of a minimum and a maximum diameter of at least one of the inner wall and the outer wall of said tubular tissue structure, along the midline of the tubular tissue structure in the first volume data record and along the midline of the tubular tissue structure in the second volume data record; and establishing at least one change in at least one of the minimum and the maximum diameter of at least one of the inner wall and the outer wall of said tubular tissue structure, 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.
