Compton camera three-dimensional simulation and experimental data

The dataset consists of two parts: three datasets simulated using GATE v9.2 software, all of which are simulations of 662keV photon sources, including point sources, six sphere linearity sources, and complex 3D extension sources, where the complex 3D extension source contains data from four perspectives; There are also three datasets obtained from actual detection using H3D's M400 detector, namely detection data of two Na22 sources at different distances, four view detection data of three Co60 sources, and datasets of simultaneous detection of one Cs137, one Co60, and one Na22 source in large space, as well as reconstruction results of MLEM, 3D UNet, and ComptonGS for these datasets
