提出了一套标准的性能测量与正电子发射断层扫描仪使用。这套测量方法是由核医学学会计算机与仪器理事会和国家电气制造商协会联合开发的。测量包括空间分辨率、散射分数、灵敏度、计数率损失和随机性、均匀性、散射校正、衰减校正和计数率线性校正的测试。
A standard set of performance measurements is proposed for use with positron emission tomographs. This set of measurements has been developed jointly by the Computer and Instrumentation Council of the Society of Nuclear Medicine and the National Electrical Manufacturers Association. The measurements include tests of spatial resolution, scatter fraction, sensitivity, count rate losses and randoms, uniformity, scatter correction, attenuation correction, and count rate linearity correction.
