摘要: A method for segmenting tubular structures in medical images includes providing (62) at least a start point and an end digital image volume, minimizing (63) action surface U0(p) which, each p, corresponds to minimal energy integrated along path that starts p0 ends sliding back (64) on the from find connecting terminal points, initializing(65) level set function with points path, evolving (66) of structure about wherein is constrained be close signed distance prevented growing wider than predetermined diameter R, defines structure.
