Collimated radiation detector assemblies, arrays of collimated radiation detectors and a collimated radiation electrode module are provided which offer the advantages of high gamma ray energy resolution and good gamma ray collimation for imaging capability. A conductive metal structure acts as an electromagnetic shield to produce the Frisch grid effect in a solid-state detector crystal or substrate of a detector. The structure may be a single structure or two parts connected together. The structure improves the gamma ray energy resolution response while at the same time serving as a gamma ray directional collimator. The assemblies, arrays and module can be manufactured from a variety of materials, including common semiconductors such as silicon, germanium, and cadmium-zinc-telluride. Assemblies can be stacked to produce a gamma ray imaging array. Also, various structures having several compartments for detectors or detector portions are provided.
