System and method for compressing and/or reconstructing medical image

Abstract

A method for compressing a 3D medical image includes the steps of receiving a 3D medical image, partitioning the 3D medical image into a plurality of first slices, encoding the plurality of the first slices by a lossy codec into first bitstreams, decoding the first bitstreams by the lossy codec to obtain a plurality of second slices, computing a plurality of residues by comparing the plurality of the first slices and the plurality of the second slices, encoding the plurality of the residues by a lossless codec to obtain a plurality of encoded residues, and outputting the first bitstreams and the plurality of the encoded residues as compressed image data. Each residue corresponds to one of the first slices and its corresponding second slice. Experimental results on prevailing 3D medical image datasets demonstrate that the proposed method achieves promising compression performance and outperforms state-of-the-art methods.
