RESUMO

Breast cancer is one of the main causes of women death all over the world. However, early detection of the disease increases greatly the possibility of cure. Therefore, several types of computer systems based on image processing are being developed by many research groups in order to aid the radiologist in the accuracy of the diagnosis. The work presented here is inserted in this context corresponding to the development of a computer system designed to detect microcalcifications clusters - structures which can be a strong indicative of breast cancer. This system database is digitized mammograms, to which image processing techniques are applied in order to detect regions of interest and the possible clusters. The results from the tests have shown an efficacy of 94% of the system in clusters correct identification.
