标题： An EDUGATE simulation toolkit based on the educational easyPET

摘要： EasyPET是一种新型的正电子发射断层扫描（PET）扫描仪，采用了基于两个旋转轴的探测器对运动的创新采集方法。 由于其简单性，它适用于教育目的，可以用来教学生关于PET技术及其基本概念，从辐射检测和模拟脉冲分析到符合排序和图像重建。 该概念通过消除由相互作用深度（DOI）引起的视差误差来实现整个视野（FoV）内的高且均匀的位置分辨率，这是基于环的PET系统的典型问题，因此即使没有最先进的图像重建算法也能获得高质量的图像。 在阿威罗大学开发并在申请专利的技术已授权给CAEN S.p.A.，并被列入该公司的教育目录中。 在这项工作中，基于Edugate平台开发了一个仿真工具包来模拟EasyPET系统。 它可以模拟产品的所有物理方面，如扫描范围、可变视野（FOV）、闪烁体能量分辨率、符合时间和能量窗口等。 实现了一个基于滤波反投影（FBP）的简单图像重建算法。 该工具包允许课堂上快速分析仿真结果。 该平台还用于研究新的EasyPET 3D版本，并进行了NEMA NU 4-2008 IQ幻影的仿真，证明了该平台不仅可用于教育目的，也可用于研究。 阿威罗大学专利： PCT/IB2016/051487 显示英文摘要

摘要： 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.
