【発明の名称】多次元空間上の対象物データセットの分析
Document Type and Number:
Japanese Patent JP2003511126
Kind Code:
A
Abstract:
The method relates to analysis of a tubular structure 1 such as a rendition of the vascular system of a patient. Gradients g1j 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.
