Thermal regulation of tightly packed solid‐state photodetectors in a 1 mm3 resolution clinical PET system
Abstract
Silicon photodetectors are of significant interest for use in positron emission tomography (PET) systems due to their compact size, insensitivity to magnetic fields, and high quantum efficiency. However, one of their main disadvantages is fluctuations in temperature cause strong shifts in gain of the devices. PET system designs with high photodetector density suffer both increased thermal density and constrained options for thermally regulating the devices. This paper proposes a method of thermally regulating densely packed silicon photodetectors in the context of a 1 mm3 resolution, high‐sensitivity PET camera dedicated to breast imaging.
