System and method for compressing and / or reconstructing medical images

Abstract

A method of compressing a three-dimensional medical image. The method comprises the following steps: receiving a three-dimensional medical image, segmenting the three-dimensional medical image into a plurality of first slices, encoding the plurality of first slices into a first bit stream through a lossy codec, the method includes decoding a first bitstream by a lossy codec to obtain a plurality of first slices, decoding the first bitstream by the lossy codec to obtain a plurality of second slices, calculating a plurality of residuals by comparing the plurality of first slices and the plurality of second slices, encoding the plurality of residuals by the lossless codec to obtain a plurality of encoded residuals, and outputting the first bitstream and the plurality of encoded residuals as compressed image data. Each residual corresponds to a first slice and a corresponding second slice. Experimental results on an existing three-dimensional medical image data set show that the provided method has good compression performance and is superior to the most advanced method.
