Developing of Digital Mammography System For Asian Women

　

Microcalcification Detection for Computer Aided Diagnosis (CAD)

　

　

  Breast cancer

　

check01e.gif  A leading cause of death among middle-aged women.

check01e.gif  Early detection can reduce the mortality.

check01e.gif  Microcalcification is one of the earliest signs of breast cancer.

check01e.gif  Microcalcification detection is an important part in CAD system.

　

　

  Mammography

　

check01e.gif  A special kind of x-ray to visualize the internal structure of the breast.
