Analysis of an object data set on a multi-dimensional space

摘要

The method relates to analysis of a tubular structure 1 such as a rendition of the vascular system of a patient. Gradients g_1j to the surface of the tubular structure 1 are computed in a starting point (BP). Subsequently, a normal n which extends essentially perpendicularly to the gradients is derived and a cross-section is taken along a cutting plane having n as its normal. A subsequent position (VP) is taken by performing a small shift in the direction of n. The axis of the vessel is tracked by repeating the procedure.
