利用蒙特卡罗模拟方法生成了散射响应函数（SRF），并通过拟合函数对散射响应函数进行拟合，研究了散射辐射的特性。拟合函数的参数进行了研究，作为源的位置在一个充满水的圆柱体模与圆形截面的函数。SRF的参数化提供了对SPECT（单光子发射计算机断层扫描）中检测到的散射辐射的空间分布的洞察，并且有助于开发一种方法来补偿其影响，以提高SPECT图像的质量和定量精度。>
The authors have generated SRFs (scatter response functions) using the Monte Carlo simulation method and investigated the characteristics of the scattered radiation by fitting the SRFs with fitting functions. The parameters of the fitting functions were studied as a function of source position in a water-filled cylindrical phantom with circular cross section. The parametrization of the SRF provides insight into the spatial distribution of detected scattered radiation in SPECT (single-photon-emission computed tomography) and is useful in developing a method to compensate for its effects in order to improve both the quality and quantitative accuracy of SPECT images. >
