Past investigations into the characterization of a space-constrained Cs dosimetry calibration facility did not provide detailed positional measurements of gamma ray spectra. In this paper, a commercially available Compton imaging system, or imaging spectrometer, was used to accomplish this. This resulted in both spectral information and point of origin information for the measured gamma rays. The relationship between measured spectra and position was explored relative to a dosimetry phantom. The Compton equation was found to accurately describe the relationship for positions associated with larger scattering angles and was found to be less reliable for those associated with smaller angles.

使用成像光谱仪表征铯剂量计校准设备。

过去对空间受限的Cs剂量学校准工具的表征进行的研究并未提供对伽马射线光谱的详细位置测量。在本文中，使用市售的Compton成像系统或成像光谱仪来完成此任务。这样就得到了所测伽马射线的光谱信息和原点信息。相对于剂量模型，探讨了测量光谱与位置之间的关系。发现康普顿方程可以准确地描述与较大散射角相关联的位置的关系，并且对于与较小角度相关联的位置，可靠性较低。
