| 内容記述 | We provide a new viewpoint for a fundamental but little investigated problem in positron emission tomography (PET): non-collinearity of annihilation radiation from the human body. The cause of the small angular deviation from 180 deg is described as well as how to evaluate it under a spatially distrib-uted radiation source and a limited acquisition time. An elegant conversion from the photopeak spectrum into the angular distribution is done based on the conservation laws of momentum and energy to avoid problems in the direct measurement. A healthy volunteer study using 18FDG and a Ge semiconductor detector reveals the distribution as a Gaussian function with the FWHM of 0.54 deg. Finally, we calculate the physical limit of FDG-PET spatial resolution. | |||||
