Abstract

An experiment that tested our computer sys-tem for tumor detection in chest radiographs is described. The dat for this experiment consisted of forty-three chest films, twenty-four of which are normal and nineteen are abnormal. The abnormal films contain images of twenty-two verified lung tumors, We describe the performance of this system on receiver operating character-istics obtained by varying a set of design para-meters, and compare this performance to the individual and average performances of a group of eight radiologists examining the same set of films. On one of our choices of design parameters, our computer system missed 14% of the lung tumors, and produced an average of three false positives per film. The average performance among the radiologists was a miss rate of 30% with an average of 0.2 false positives per film.
