RATIONALE We previously showed that early calcification of atherosclerotic plaques associates with macrophage accumulation. Chronic renal disease and mineral imbalance accelerate calcification and the subsequent release of matrix vesicles (MVs), precursors of microcalcification. OBJECTIVE We tested the hypothesis that macrophage-derived MVs contribute directly to microcalcification. METHODS...
Breast cancer is one of the most frequently occurring disease which leads even to death among women community. The appearance of micro-calcifications in mammograms is an early sign of breast cancer. To overcome the issue, automated micro-calcification detection techniques play a vital role in cancer diagnosis and treatment. In this paper we proposed Support Vector Machine (SVM) based classifier...
In this paper we present a knowledge-based approach for the automatic detection of microcalcifications and clusters in mammographic images. Our proposal is based on using local features extracted from a bank of filters to obtain a local description of the microcalcifications morphology. The developed approach performs an initial training step in order to automatically learn and select the most ...
The most frequent symptoms of ductal carcinoma recognized by mammography are clusters of microcalcifications. Their detection from mammograms is difficult, especially for glandular breasts. We present a new system for computer-aided diagnosis of breast carcinoma, from digital mammograms. The images are processed in several steps. First, we filter the original picture with a filter that is sensi...
