This study validated a model of the Siemens Symbia T16 dual-head SPECT/CT gamma camera created using the Monte Carlo program SIMIND for Lu. The validation was done by comparing experimental and simulated gamma camera performance criteria tests for the Lu 208 keV photopeak with a medium-energy collimator. Results showed good agreement between the experimental and simulated values. These results illustrated that SIMIND could emulate the Symbia T16 successfully and therefore, can be used with confidence to model Lu images.
本研究验证了使用蒙特卡罗程序SIMIND为镥创建的西门子Symbia T16双头SPECT/CT伽马相机模型。通过比较使用中能准直器对镥208 keV光电峰进行的实验和模拟伽马相机性能标准测试来完成验证。结果表明实验值和模拟值之间具有良好的一致性。这些结果说明SIMIND可以成功模拟Symbia T16，因此，可以放心地用于对镥图像进行建模。
