Breast cancer is Europe and US and so on one of developed country woman's main death factors, also is one of malignant tumors which theworld female is most common and sends. The Chinese feminine breast cancer disease incidence rate also year by year is rising, in recent years has occupied to the malignant tumor disease incidence rate andthe mortality rate front row, becomes affects one of woman health main diseases. As the breast cancer conventional medicine image study inspection method, the mammary gland soft X photography is the early breast cancer clinical diagnosis simplest is reliable and the cost low examination method. Early malignant mammary gland tumor importantly drafts likely is the partner has tiny granulated the micro-calcification spot,promptly examines the micro calcification clinically to diagnose and treat to the early breast cancer has the vital significance. The mammary gland soft X photography by the molybdenum and so on took X ray tube the anode target surface, its launch beam is soft beam, issuitable to the soft tissue photography. Forms image the technologyand the visual limit, the specialist sometimes very difficult promptly to discover in the molybdenum target X image early breast cancer small calcification and swells the block and so on to draft the elephant, sothat delays patient's treatment opportunity. Along with the computer and its correlation technical the and so on technology rapid development and graph picture processing maturity,becomes one of hot spots based on the mammary gland soft X image computer assistance diagnosis theory and the method which at present studies. This topic was precisely has conducted the research underthis background to the mammary gland X piece automatic detect ioncanceration information related theory, to the time enhanced the early breast cancer picking out rate.Paper in view of topic division of labor and research content, through to domestic and foreign based on image guidance under computer assistance diagnosis technology research and thorough discussion, Studies each algorithm in the synthesis contrast in the foundation.The innovation proposed based on the mammary gland molybdenum targetimage computer assistance examination early time breast cancer microcalcification optimization algorithm, discussed in the mammary gland molybdenum target image to contain the calcification spot withemphasis to feel the interest region automatically to withdraw the method. Using the computer imagery processing technology, using optimized algorithm and so on wavelet transformation realized in the mammarygland X piece of picture to contain a small calcification region theautomatic detection to withdraw, and through according to hasconfirmed the algorithm feasibility with the standard picture storehouse, has provided the new algorithm attempt and the foundationfor the breast cancer early diagnosis research and a malignantdistinction.
