Objective:To avoid misdiagnosis because of doctors' fatigue caused by reading a large amount of films and to improve the efficiency and the accuracy of diagnosing the early cases of breast cancer.Methosd:Firstly mammograms were digitized;secondly digital images were normalized;thirdly some regions of interests were chosen from digital images;lastly microcalcifications were detected using difference technique and were marked in mammograms.Results:Sixteen mammograms were tested by this method,thirteen of them had been diagnosed to have microcalcification by pathological anatomy.Results showed that microcalcifications were detected in fourteen mammograms using this method.Conclusion:This method can achieve a true positive rate and microcalcifications were located well and truly.So the method is worth to be researched further.
