Scalable compression of volumetric images

Scalable compression of volumetric images
An important problem in medical imaging is that of ef?cient volumetric image compression. In addition to compression ef?ciency, scalable representations which allow access to the data at various qualities up to and including lossless reproduction are particularly important. Also important is the ability to access local regions of the volumetric data set or to alter the ?delity or resolution with which a selected region is accessed. In this paper, we ?rst consider bounds to the ef?cacy of three dimensional transform techniques. We then propose a particular technique, based on motion adaptive wavelet lifting, which is able to realize the goals of high compression ef?ciency, lossy to lossless scalability, and ef?cient random access, all within a single compressed data stream.
