Abstract

Various high-resolution scintillation detectors are analyzed for resolution and sensitivity. In particular, the effects of using a wedge face and inter-crystal tungsten-septa are studied for both BaF2 and BGO crystals. The results indicate that usage of septa alone causes an improvement in resolution in areas away from the center of the image, but also causes a degradation in sensitivity in those areas, and that usage of a wedge face alone causes no improvement in resolution, while usage of septa and a wedge face in combination causes a similar resolution improvement, but with a lesser degradation in sensitivity.
