A method is introduced for the evaluation of x-ray spectra from x-ray machines operating in the range 50-100 kVp using a cadmium telluride (CdTe) detector with low detection efficiency. The pulse height distribution obtained with this kind of detector does not represent the true photon spectra owing to the presence of K-escape, Compton scattering, etc.; these effects were evaluated using a Monte Carlo method. A stripping procedure is described for implementation on a Univac 1100/82 computer. The validity of our method was finally tested by comparison with experimental results obtained with a Ge detector and with data from the literature; the results are in good agreement with published data.
介绍了一种使用探测效率较低的碲化镉（CdTe）探测器来评估工作在50 - 100 kVp范围内的X射线机的X射线光谱的方法。由于存在K逃逸、康普顿散射等情况，用这种探测器获得的脉冲高度分布并不代表真实的光子光谱；这些效应是用蒙特卡罗方法评估的。描述了一种在Univac 1100/82计算机上实施的剥离程序。最后通过与用锗探测器获得的实验结果以及文献数据进行比较，检验了我们方法的有效性；结果与已发表的数据高度吻合。
