Abstract

Mammograms are frequent detection means in breast disease. But the limited bandwidth impedes the communication transmission of mammograms in PACS. In this paper, we investigated on the compression method of four mammograms in DICOM format in narrow band transmission environment. Firstly, according to the similarity of mammograms at the same view, the difference of two images can be obtained by making subtraction between the two images after reversal and reference images. Then, an improved Sobel method was proposed to achieve the edge detection of mammograms and also to extract the region of interest (ROI). Finally, using the run-length coding which is one of the entropy coding to process the lossless compression coding for the ROI of the difference images. In this paper, the compression method proposed is proved on the actual mammograms, and the better compression ratio was obtained at mammograms of CC views and MLO views.
