AUTOMATED METHOD AND SYSTEM FOR THE DETECTION OF ABNORMALITIES IN SONOGRAPHIC IMAGES

摘要

A method of detecting a candidate abnormality in a sonographic medical image, based on determining a radial gradient index (RGI) at plural pixels, producing an RGI image, thresholding the RGI image (S106), determining a candidate abnormality (S108) based on the thresholding step (S106), and locating a center point of the candidate abnormality (S112). The candidate abnormality may be classified by segmenting the candidate abnormality, including determining average radial gradients (ARDs) in the sonographic medical image (S114) based on the center point and feature extraction (S116) and determining the likelihood of being an actual abnormality (S120).
