Dataset for "Multi-photon time-of-flight MLEM application for the positronium imaging in J-PET"

Dataset used to reconstruct an image of 4-sources. Simulated using J-PET Geant4 and analyzed with the J-PET Framework.
In the form of X position [cm], Y position [cm], Z position [cm], Time [ps]for every hit in an event and as folowsdeexcitation hit, first annihilation hit, second annihilation hit

本数据集用于重建四源图像，采用J-PET Geant4进行模拟，并通过J-PET框架完成数据分析。其数据格式为每个事件中每一次击中的X位置[cm]、Y位置[cm]、Z位置[cm]与时间[ps]，具体分为退激发击中、首次湮灭击中与第二次湮灭击中三类。
