TL;DR: In this paper, a whole-body positron emission tomography (PET) system based on plastic scintillators is developed by the J-PET Collaboration, and the spatial resolution, sensitivity, scatter fraction and noise equivalent count rate are estimated according to the National Electrical Manufacturers Association norm, as a function of the length of the tomograph, the number of detection layers, the diameter of the computed tomographic chamber and for various types of applied readout.
