With the rapidly growing use of digital images in medical archival and communication, image compression technology, especially diagnosis lossless compression technology, plays a more and more important role for medical applications.In this thesis, a novel diagnosis loseless compression algorithm is presented for digital mammography.The mammogram is divided into breast region, pectoral muscle and background using the CAD technology.Then mutiple arbitrary shape ROIs coding framework is used to compress the mammogram in which the breast region and pectoral muscle are compressed losslessly and lossily respectively, and the background can be discarded or compressed lossily as user's will.Experimental results show that the proposed method offer potential advantage in medical applications of digital mammography compression.
