摘要： An x-ray detector module including a silicon photomultiplier and a computed tomography imaging system including the same is provided. The x-ray detector module includes optically coupled scintillation materials and silicon photomultiplier pixels. The x-ray detector pixels may have a constant axial profile with a polygonal cross section, which may be rectangular. A plurality of the x-ray detector pixels are generally arranged into 2D arrays. Each x-ray detector pixel may be connected to a dedicated electronic readout channel. In operation, the scintillation materials interact with incident x-ray photons to generate visible-light photons. The silicon photomultiplier pixels generate electrical signals in accordance with the number of visible-light photons generated by an incident x-ray photon. The electronic readout channels process the electrical signals to determine characteristics of the incident x-ray photons. Information of a plurality of x-ray photons are compiled to generate computed tomography images.

摘要： An avalanche drift photodetector (ADP) incorporates extremely low capacitance of a silicon drift photodetector (SDP) and internal gain that mitigates the surface leakage current noise of an avalanche photodetector (APD). The ADP can be coupled with scintillators such as CsI(Tl), NaI(Tl), LSO or others to form large volume scintillation type gamma ray detectors for gamma ray spectroscopy, photon counting, gamma ray counting, etc. Arrays of the ADPs can be used to replace the photomultiplier tubes (PMTs) used in conjunction with scintillation crystals in conventional gamma cameras for nuclear medical imaging.

摘要： A radiation detector system having a heat pipe based cooling. The radiation detector system includes a radiation detector thermally coupled to a thermo electric cooler (TEC). The TEC cools down the radiation detector, whereby heat is generated by the TEC. A heat removal device dissipates the heat generated by the TEC to surrounding environment. A heat pipe has a first end thermally coupled to the TEC to receive the heat generated by the TEC, and a second end thermally coupled to the heat removal device. The heat pipe transfers the heat generated by the TEC from the first end to the second end to be removed by the heat removal device.
