摘要：
在先前的出版物中，我们提出了一种基于探测过程蒙特卡洛模型的替代方法，用于确定调制传递函数（MTF）、噪声功率谱（NPS）和探测量子效率（DQE）等关键探测器特性。若能获得针对光子入射到像素不同位置时探测器响应的蒙特卡洛模型，即可直接推导得到探测器的完整统计特性。本文旨在详细阐述该方法，并将其应用于四类实际探测器：采用CdTe和硅的直接转换探测器、带有额外符合计数器的CdTe光子计数器，以及以LaBr3为闪烁体的光学计数系统。
英文摘要：
In previous publications, we have presented an alternative approach to determine essential detector properties like the Modulation Transfer Function (MTF), the Noise Power Spectrum (NPS) and the Detective Quantum Efficiency (DQE) based on a Monte Carlo model of the detection process. If a Monte Carlo model for the detector response to photons impinging at various locations of a pixel is available, the full statistics of the detector can be derived in a straightforward manner. The purpose of this paper is to describe the method in detail and to apply it to four types of realistic detectors: direct converting detectors using CdTe and silicon, a CdTe photon counter with additional coincidence counters and an optical counting system using LaBr3 as scintillator.
