Abstract
The Cramer-Rao lower bound on estimator variance is used as a tool for assessing radiation detector requirements for nuclear medicine imagin g. The classical bound for unbiased estimators is reviewed and its rel ationship to the well-known propagation-of-error formula is demonstrat ed. The uniform Cramer-Rao bound is described for situations where unb iased estimation is impractical such as in tomographic imaging. The bo unds are used to evaluate the necessary detector requirements for a Cs I(Tl)/Si photodiode scintillation camera, and to compare the performan ce of a Compton-scatter camera to that of a parallel-hole collimator/A nger camera system.
