质子治疗过程中的束内SPECT是一种新的三维体内剂量验证方法。为此，康普顿相机的设计是根据这一应用产生的特殊要求和条件进行评估的。通过仿真研究了不同的角度分辨率和效率概念。研究发现，碲化锌镉体系可以很好地发挥作用。为了进一步评估，正在建造一个半导体闪烁体混合系统。(C)2010爱思唯尔B.V.保留所有权利。
In-beam SPECT during therapeutic proton beam irradiation is a novel method for three dimensional in-vivo dose verification. For this purpose a Compton camera design is evaluated with respect to the special requirements and conditions that arise from this application. Different concepts are studied by means of simulation concerning the angular resolution and efficiency. It was found that a cadmium zinc telluride system can perform sufficiently well. For further evaluation the construction of a semiconductor scintillator hybrid system is under way. (C) 2010 Elsevier B.V. All rights reserved.
