Adaptative hit-or-miss region growing for vessel segmentation in medical imaging

摘要

The present invention concerns a method for the segmentation of vessel trees in 3D medical images, comprising steps of:- defining an initial seed corresponding to a first identified point, said seed being a point of the 3D image corresponding to a vessel,- performing region-growing segmentation by iteratively (i) identifying points in the neighborhood of previously identified points which belongs to vessels by using an identification criterion based on the application of a grey-level Hit-or-Miss Transform (HMT) with a set of structuring elements of a template size, and (ii) adding the identified points to the segmented vessel tree.;The region-growing segmentation is repeated iteratively for different template sizes.;The present invention concerns also a computer program implementing the method.
