A Hybrid Lossless Compression Scheme for Efficient Delivery of Medical Image Data over the Internet

Medical imaging applications generate large volumes of medical data leading to challenges for transmission and storage. In this paper, a novel lossless 3D compression scheme for medical image delivery is proposed. It is based on Prediction by Partial Matching (PPM) in combination with 3D JPEG-4 compression. This scheme is intended for accelerating the delivery of data over the Internet and consequently we are concerned with both compression ratio and decompression time. Experimental results illustrate that the proposed scheme is efficient and feasible in terms of both compression ratio and decompression speed.
