SYSTEM AND METHOD FOR CORRECTING IMAGING SYSTEM MEASUREMENT BIAS FROM NON-STATIONARY NOISE IN MODEL OBSERVERS

摘要

Systems and methods for correcting images acquired with an imaging system for measurement bias from non-stationary noise in model observers are described. A biased detectability index is estimated from signal present and signal absent condition images and an estimate of the bias from non-stationary noise is also estimated. This bias is then removed from the detectability index to provide an assessment of detectability of the imaging system.
