A combined γ-ray probe/γ+ imaging detector was created through the modification of a beta imaging intra-operative probe. The phoswich detector consists of a thin CaF2(Eu) β+ imaging disk, coupled through a light diffuser to 7 or 19 parallel-piped high-Z scintillation crystals arranged hexagonally in columns. The performance characteristics of the assembled prototype devices demonstrate that in surgery, this device can be used for: the rapid localization of γ emitting radionuclides with the modestly directional, self-collimated phoswich crystals; high-resolution β- imaging or coarse β+ imaging in singles mode; or β+ imaging in coincidence mode with reduced γ background contamination.
