通过在体模和临床成像研究中进行的测量，对Super PETT I的物理特性和某些成像能力进行了实验评估。Super PETT I是一种在图像重建过程中利用飞行时间（TOF）的正电子发射断层扫描仪。评估的性能特征包括灵敏度、空间分辨率、飞行时间信息利用率带来的图像改善、系统死区时间和线性度。临床实例包括大脑、心脏、肝脏的成像，以及Super PETT I实现心脏门控能力的演示。
The physical characteristics and some imaging capabilities of Super PETT I, a positron emission tomograph utilizing time-of-flight (TOF) in its image reconstruction process were assessed experimentally by means of measurements carried out in phantoms and clinical imaging studies. The performance characteristics assessed included sensitivity, spatial resolution, image improvements resulting from time-of-flight information utilization, system dead time, and linearity. The clinical examples included imaging of the brain, the heart, the liver, and a demonstration of Super PETT I's capability of achieving cardiac gating.
