高分辨率成像伽马射线探测器是使用Hamamatsu的5”直径R3292位置敏感PMT（PSPMT）和各种晶体闪烁体阵列开发的。特殊的读出技术被用来最大限度地提高有效成像面积，同时减少读出通道的数量。空间分辨率接近1毫米，在一个广泛的能量范围从20至511千电子伏。结果还提出了耦合的闪烁体阵列的PMT通过成像光导组成的丙烯酸光纤，使更大的设计自由度。
High resolution imaging gamma-ray detectors were developed using Hamamatsu's 5" diameter R3292 position sensitive PMT (PSPMT) and a variety of crystal scintillator arrays. Special readout techniques were used to maximize the active imaging area while reducing the number of readout channels. Spatial resolutions approaching 1 mm were obtained in a broad energy range from 20 to 511 keV. Results are also presented of coupling the scintillator arrays to the PMT via imaging light guides consisting of acrylic optical fibers which enables greater design freedom.
