  EasyPET is a new concept of a Positron Emission Tomography (PET) scanner
using an innovative acquisition method based on two rotation axes for the
movement of detector pairs. Due to its simplicity, it is suitable for education
purposes, to teach students about the PET technology and its basic concepts,
from the radiation detecting and analogue pulse analysis to the coincidence
sorting and image reconstruction. The concept allows achieving high and uniform
position resolution over the whole field of view (FoV), by eliminating parallax
errors due to the depth of interaction (DoI), which are typical of ring-based
PET systems, so quality images are obtained even without state-of-the-art image
reconstruction algorithms. The technology developed at the University of Aveiro
with a patent-pending, is licensed to CAEN S.p.A, and included in the
educational catalogue of the company. In this work, a simulation toolkit based
in the Edugate platform was developed to simulate the EasyPET system. It can
simulate all the physical aspects of the product, such us the scanning range,
variable Field-of-View (FOV), scintillator energy resolution, coincidence time
and energy window, among others. A simple image reconstruction algorithm based
on Filtered-back-projection (FBP) is implemented. The toolkit allows a quick
analysis in classroom of the simulation results. The platform was also used to
study the new EasyPET 3D version, and a simulation of a NEMA NU 4-2008 IQ
phantom was performed, demonstrating the capability of the platform not only
for education purposes but also for research. Patent Universidade de Aveiro:
