Abstract

Describes a mathematical method to detect and to characterize microcalcifications in mammographic images, using the Hough transform. This method will allow radiologists not only to examine digitized and filtered images, but also to take advantage of a method which will assist them in their diagnoses. Identification of ring-shaped and vermiculated microcalcifications associated to non-malignant and malignant tumors is provided
