Abstract

To develop a second generation gamma-ray camera for industrial applications, various multiple-hole collimator designs that meet high-energy, high-intensity and far-field imaging requirements have been studied. The collection of parallel holes each parallel to one another (parallel-hole, parallel collimator) is ineffective for imaging high energy far-field sources, whereas a collimator with parallel holes arranged in a diverging manner (parallel-hole, diverging collimator) is a good candidate for our imaging system. The response of a proposed collimator to different source conditions is modelled and presented in this work
