Abstract

An ideal observer is a mythical detector optimized to give the best performance for a given signal detection or discrimination task. 'Best' is defined here to mean that the detector is designed to yield the lowest possible Bayesian risk. The signal-to-noise ratio can be measured at the output of an ideal detector, which we will call SNR //i//d//e//a//l, and used as a figure of merit for a medical imaging system. For SNR//i//d//e//a//l to be a meaningful metric for medical images it must predict the ability of a human observer to perform the same detection or discrimination task. Images have been generated with equal ideal-observer SNR's but different autocorrelation functions to test the applicability of ideal-observer SNR for predicting human observer performance for images of different noise textures.
