西门子ECAT EXACT HR＋型PET的性能测试和质量控制

目的：全面评估我院使用多年的PET仪的性能参数，保证图像质量以及性能参数的稳定。方法：参考美国国家电气制造商学会（NEMA）布的PET性能测试NEMA NU2—1994标准。使用NEMA标准圆柱模型、18F放射源、18F和68Ge的柱源。结果：草拟了一套性能测试方案和日常质量控制方案。结论：这套方案对PET仪的性能测试和日常质量控制提供了参考依据和方法步骤，这些将能更好地保证PET仪的图像质量及性能参数的稳定。

Performance Tests and Quality Control of Siemens ECAT EXACT HR+ PET

Objective To evaluate the performance parameters of the PET instrument, which has been used for years in our hospital, assuring the stability of image quality and performance parameters. Methods NEMA NU 2-1994 Standards was used as reference for performance measurement of PET, which were published by National Electrical Manufacturers Association(NEMA). The NEMA standard cylinder model, 18F radiation source, and 18F and 68Ge columniform radiation source were used. Results Projects for performance measurement and daily quality control were drawn up. Conclusion This project provides a reference and methods for the performance measurement of PET instrument and daily quality control. It better ensures the stability of image quality and performance parameters of the PET instrument.
