AUTOMATED METHOD AND SYSTEM FOR COMPUTERIZED DETECTION OF MASSES AND PARENCHYMAL DISTORTIONS IN MEDICAL IMAGES

摘要

A method and system for automated detection of lesions such as masses and/orparenchymal distortions in medical images such as mammograms. Dense regionsand subcutaneous fat regions (102) within a mammogram (100) are segmented(101). A background correction may be performed within the dense regions.Hough spectrum within ROIs (104) placed in the breast region of a mammogram(100) are calculated and thresholded (106) using the intensity value in orderto increase sensitivity and reduce the number of false-positive detections.Lesions are detected based on the thresholded Hough spectra. The thresholdedHough spectra are also used to differentiate between benign and malignantmasses.
