A Gamma Camera Probe with Hybrid Photodiode Readout

Abstract

The application of newly emerging multi-pixel Hybrid Photodiode tubes as the basis for a compact clinical gamma camera is proposed. The characteristics of this camera system are discussed and an optimised design presented. Compared to existing clinical gamma cameras, this system is expected to offer an improved spatial resolution without a significant deterioration in the detection efficiency and energy resolution. A comparison is made of multi-pixel Hybrid Photodiodes and Position Sensitive Photomultiplier Tubes.
