Paper Abstract

To make the archival and transmission of medical images in PACS (Picture Archiving and Communication Systems) and teleradiology systems user-friendly and economically profitable, the adoption of an efficient compression technique is an important feature in the design of such systems. An important category of lossy compression techniques uses the wavelet transformation for decorrelation of the pixel values, prior to quantization and entropy coding. For the coding of sets of images, the images are mostly independently compressed with a two-dimensional compression scheme. In this way, one discards the similarity between adjacent slices. The aim of this paper is to compare the performance of some two- dimensional and three-dimensional implementations of wavelet compression techniques and investigate some design issues as decomposition depth, the choice of wavelet filters and entropy coding.
