Abstract :
Mammography is still the major tool for screening and diagnostic examinations of early breast cancer detection. It gives opportunities for early detection of breast cancer. For early detection of breast cancer, the mass visuality of mammography is very important. Direct mapping is suggested through which the breast radiography relates to the reference phantom radiography by finding the closest intensity values between those radiography images at both energy. With the proposed method, we could enhance the visuality of mass lesions in breast. And the results show that the proposed method has good performance, showing the possibility of cancer detection mammography.
