Abstract
A data compression system for use in processing diagnostic image data which combines delta modulation with coding the most prevelant difference by a code other than a least bit code but coding the most prevalent number of strings with a least bit code and also coding the next most common differences with a least bit code and subsequent most common differences with sequentrial least bit codes to provide compression ratios of over 3:1.
