    Towards Automated Semantic Segmentation in Mammography Images

    Mammography images are widely used to detect non-palpable breast lesions or nodules, preventing cancer and providing the opportunity to plan interventions when necessary. The identification of some structures of interest is essential to make a diagnosis and evaluate image adequacy. Thus, computer-aided detection systems can be helpful in assisting medical interpretation by automatically segmenting these landmark structures. In this paper, we propose a deep learning-based framework for the segmentation of the nipple, the pectoral muscle, the fibroglandular tissue, and the fatty tissue on standard-view mammography images. We introduce a large private segmentation dataset and extensive experiments considering different deep-learning model architectures. Our experiments demonstrate accurate segmentation performance on variate and challenging cases, showing that this framework can be integrated into clinical practice.Comment: 6 page

    Pre-processing of mammograms is a crucial step in computer-aided analysis systems. The aim of segmentation is to extract a breast region by estimation of a breast skin-line and a pectoral muscle as well as removing radiographic artifacts and the background of the mammogram. Knowledge of the breast contour also allows further analysis of breast abnormalities such as bilateral asymmetry. In this paper we propose a fully automatic algorithm for segmentation of a breast region, based on two types of global image thresholding: the multi-level Otsu and minimizing the measure of fuzziness as well as the gradient estimation and linear regression. The results of our experiments showed that our method can be used to find a breast line and a pectoral muscle accuratel

    Breast Cancer: Research and Treatment

    We seek to understand and treat cancer to reduce a major source of human suffering. Cancer is a plague of our generation, one of the last incurable diseases. It is interesting to note that past generations did not generally live long enough to suffer from cancer. Infectious disease drastically limited the human life span. In recent history, western medicine has been able to control infection and life expectancy has risen dramatically. Cancer is the next hurdle. Modem research slowly gains insight with the hope of finding new ways to control cancer. This paper provides information about the process by which cancer develops and how the disease can be treated. The paper begins with a discussion of the plausible causes for cancer. Then, explanations of how cancer works at a cellular level will help the reader think about cancer in the same framework as modem cancer researchers. Next, some of the current pursuits of cancer research are explored. In order to provide more specific information, the focus narrows to breast cancer. New discoveries and experimental pursuits are discussed. The last section of this paper explains the process a breast cancer patient might go through as breast cancer is diagnosed and treated

    Mammography Techniques and Review

    Mammography remains at the backbone of medical tools to examine the human breast. The early detection of breast cancer typically uses adjunct tests to mammogram such as ultrasound, positron emission mammography, electrical impedance, Computer-aided detection systems and others. In the present digital era it is even more important to use the best new techniques and systems available to improve the correct diagnosis and to prevent mortality from breast cancer. The first part of this book deals with the electrical impedance mammographic scheme, ultrasound axillary imaging, position emission mammography and digital mammogram enhancement. A detailed consideration of CBR CAD System and the availability of mammographs in Brazil forms the second part of this book. With the up-to-date papers from world experts, this book will be invaluable to anyone who studies the field of mammography
