The present invention relates to the bendings that a kind of method is used to determine blood vessel, comprising: a 3-D image, obtaining step and obtaining a 3-D image includes labelled reagent One reference point selecting step is selecting 2 different reference voltage points from the 3-D image that 3-D image obtains, is obtaining step One scalar value determines step, and a scalar value is determined between the reference point selected from reference point selecting step One vector value determines step, and a vector value is determined between the reference point selected from reference point selecting step Between reference point determine it is curved one be bent determine step, by determined by scalar value step and vector value determine step determine reference point between use scalar value and vector value.Copyright KIPO 2017
