摘要：
Size of volumetric medical images is very large. Because of this, some problems occur while storing or transmitting this type of data. So, it is necessary to compress volumetric medical images using efficient techniques. It is more appropriate to compress medical images using lossless techniques due to it may have effects on diagnosis. In this study, a method for lossless compression of volumetric medical images was proposed. The redundancy has been reduced using DPCM technique by utilizing correlation between image slices. SAP technique has been applied to first slice. The performance is improved by applying RDPCM for each image frame after DPCM, individiually. To investigate the performance of the proposed method, some experiments have been performed using different medical images and the results are presented.
