Abstract

In the optimization of a collimator of a scintigraphic system there are two main features to take into account: the spatial resolution and the sensitivity. In general the collimator design has been studied independently from the other components of the system and it has been tried either to improve one of these characteristics, generally the sensitivity for a given resolution,or to find a compromise between them [1,2,3]. SIMMONS et al. [4] proposed an optimization method based on the sentivity and on the MTF of the total system. It was applied to obiects with the shape of infinite cylinders, placed at a given distance from the collimator. ROLLO [5] introduced an index to compare the performance of scintigraphic imaging systems. This index combines the contrast efficiency function with the plane sensitivity.
