Method and branching - determining device for determining a branch point as well as a center line within a hollow organ in addition to an associated computer program

摘要

The present invention relates to a method for determining a branch point (v) within a hollow organ (1) in the image data (bd), which represent the spatial structure. It comprises the following steps: a) determination of a start location (5) within the hollow organ (1), b) determination of at least one local threshold value (s_u, S_o), the with the presence of a wall of the hollow organ (1) corresponds, c) carrying out a regions - growth - method using of the at least one threshold value (s_u, S_o), d) carrying out a correlation analysis of a number of external growth of layers, and e) of locating a branch (v) on the basis of the coherence analysis. Moreover, the invention relates to a correspondingly shaped branching - determination unit (23).
