Abstract:

The primary goal of this project was the development of a clinical experimental protocol for evaluating the comparative quality of analog, digital, and lossy compressed digital mammograms in a manner not suffering from the fundamental flaws of traditional receiver operating characteristic ROC methods. Such a protocol was developed and implemented in a pilot experiment involving 57 patients and six radiologist judges interpreting original. The protocol, experiment, and results are described along with related algorithms for compression and combined compression and classification.
