SYSTEM AND METHOD FOR AUTOMATIC SEGMENTATION OF VESSELS IN BREAST MR SEQUENCES

摘要

A method for segmenting digitized images includes providing (61) a digitizedimage, selecting (62) a point with a median enhancement greater than apredefined threshold, wherein a contrast enhancing agent was applied to thesubject matter of said digitized image prior to acquisition of said image,defining (63) a shape matrix for the selected point in said image from momentsof the intensities in a window of points about said selected point,calculating (64) eigenvalues of said shape matrix, determining (65) aneccentricity of a structure underlying said point from said eigenvalues, andsegmenting (67) said image based on said eccentricity values, wherein thesteps of defining a shape matrix, calculating eigenvalues of said shapematrix, and determining the eccentricity of the underlying structure arerepeated (66) for all points in said image.
