Medical imaging has started to take advantage of digital technology
opening the way for advanced medical imaging and teleradiology. Medical images
however
require large amounts of memory. At over 1 million bytes per image
a typical hospital needs a staggering amount of memory storage (over one trillion bytes per year)
and transmitting an image over a network (even the promised superhighway) could take minutes - too slow for interactive teleradiology. This calls for image compression to reduce significantly the amount of data needed to represent an image. Several compression techniques with different compression ratio have been developed. However
the lossless techniques
which allow for perfect reconstruction of the original images
yield modest compression ratio
while the techniques that yield higher compression ratio are lossy
that is
the original image is reconstructed only approximately Medical imaging poses the great challenge of having compression algorithms that are lossless (for diagnostic and legal reasons) and yet have high compression ratio for reduced storage and transmission time. To meet this challenge
we are developing and studying some compression schemes
which are either strictly lossless or diagnostically lossless
taking advantage of the peculiarities of medical images and of the medical practice. In order to increase the Signal to-Noise Ratio (SNR) by exploitation of correlations within the source signal
a method of combining differential pulse code modulation (DPCM) is presented.
