We present the results of a study of error free compression of digitized medical x-ray images. This study used high resolution (2048 x 1684), high quality (8 to 11 bits per pixel) images, each approximately 5 Mbytes before compression. Since the medical community is very reluctant to introduce unnecessary noise into their imaging, we require error-free compression or, equivalently, perfect reconstruction. In particular, we investigated the following error free methods: Huffman coding, arithmetic coding, Lempel-Ziv coding, runlength coding, ordinary quadtree coding, and a new quadtree method, multi-window quadtree.
