Summary
This work deals with the optimum compression rates that can be obtained by means of two DCT coding techniques in order to preserve the radiograms “diagnostic information”.
The results of a quality analysis of compressed digitized radiographics images of incomplete fractures are presented. A consistent meaningful set of radiograms was coded by Bordoni Foundation in Rome and quality tested by a team of radiologists working at the Radiology Department of the University of Pisa.
ROC curves [7] were obtained from the results of the observations of trained radiologists who analyzed the compressed images without any previous knowledge of the algorithms used for coding.
