Analysis Of Dqe And Neq Measurement Errors For Medical Imaging Systems

Recent work aimed at quantifying the statistical efficiency of diagnostic imaging systems has resulted in the frequent use of the detective quantum efficiency (DQE) and noise equivalent quantum exposure (NEQ). Estimation of these metrics requires the separate measurement of several imaging parameters. An analysis is given which results in expressions for DQE and NEQ estimate errors in terms of component measurement error statistics.
