摘要

摘要我们报告了对具有不同表面的单片位置敏感探测器的模拟和分辨率评估。最佳结果是将晶体表面的粗抛光与特氟龙包裹层相结合，相互作用深度的分辨率为 dZ = 0.89 ± 0.01 毫米。最佳的平面分辨率 dX = 0.53 ± 0.01 毫米是在带有 ESR 膜的精细抛光板上获得的。与镜面反射器相比，漫反射器的集光率也提高了 33%。

Optimization of a Scintillation Detector for Positron Emission Tomography

We report simulation and resolution evaluation of monolithic position sensitive detectors with different surfaces. The best result was obtained using a combination of rough polishing of the crystal surface and a Teflon wrapper with a resolution in the interaction depth of dZ = 0.89 ± 0.01 mm. The best planar resolution dX = 0.53 ± 0.01 mm is obtained for a finely polished plate with an ESR film. The diffuse reflector also demonstrates an increase in light collection by 33% compared to the specular one.
