Abstract

The transmission of digitized medical images over the existing telecommunications infrastructure presents a formidable challenge. To achieve delivery times on the order of seconds--as opposed to minutes or hours--for large-format high-resolution images, data compression on the order of 25:1 is necessary. This degree of data compression cannot be reached with lossless techniques. This paper reports on an adaptation of a standardized technique for lossy image compression (the JPEG approach), which provides high compression ratios for radiographic images with minimal apparent loss of diagnostic quality.
