Abstract

This paper presents a detection method of microcalcifications clusters with arbitrary shapes in digital mammography images. In the proposed method, the suspicious regions are marked according to the locations of the microcalcifications in the breast. This approach can help experts in mammogram analysis, since the microcalcification cluster shape is an important clinical attribute, and improve the performance of computational methods. Initial results in relation to circular ROIs (Regions Of Interest) show that the proposed method reduces the amount of ROI data, on average, 76%, 67% and 62% for glandular, fat and dense breast tissue, respectively, without significant loss in microcalcifications.
