通过采用来自发射第三瞬发光子的β衰变同位素的γ轨迹交叉点之间的三重重合(γ-PET技术),可以在3维中达到亚毫米空间分辨率以用于点源的定位,与常规PET重建分析相比,每个体素的重建交叉点的要求降低。结果的蒙特-卡罗模拟和图像重建研究,以表征这种技术的潜力。
By employing the triple coincidence between the γ trajectory intersections from β decaying isotopes emitting a third, prompt, photon ( γ-PET technique), sub-millimeter spatial resolution can be reached in 3 dimensions for the localization of a point source with a reduced requirement of reconstructed intersections per voxel compared to a conventional PET reconstruction analysis. Results of a Monte-Carlo simulation and image reconstruction study are presented in order to characterize the potential of this technique.
