<p>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 ñ which extends essentially perpendicularly to the gradients is derived and a cross-section is taken along a cutting plane having ñ as its normal. This cross-section is used to iteratively evaluate the center position of the tubular structure. A subsequent position (VP) is taken by performing a small shift in the direction of ñ. The axis of the vessel is tracked by repeating the procedure. An eventual reservoir (e.g. aneurysm) is separated from the tubular structure and its volume calculated.</p> |
