最近开发的Geant 4应用程序断层扫描发射（GATE）工具包是一个Monte Carlo模拟平台，为PET和SPECT模拟开发，并由OpenGATE合作免费分发。GATE提供了模拟时间相关现象的能力，例如几何元素运动和源衰减动力学，允许在现实采集条件下模拟时间曲线。本文的目的是验证西门子PET Biograph（TM）6扫描仪模拟的GATE模型。该三维GATE模型模拟了24336个LSO（氧硅酸镥）探测器，根据供应商的规格分为144个模块。门的结果进行了比较与实验数据，获得按照NEMA NU 2-2001性能测量协议。该方案使用的散射体模也在GATE中建模，使我们能够模拟散射分数和计数率性能测量。(c)2006 Elsevier B.

The recently developed Geant4 Application for Tomographic Emission (GATE) toolkit is a Monte Carlo simulation platform developed for PET and SPECT simulations and is freely distributed by the OpenGATE collaboration. GATE provides the ability of modelling time-dependent phenomena, such as geometry element movements and source decay kinetics, allowing the simulation of time curves under realistic acquisition conditions. The purpose of this paper was to validate a GATE model for the simulation of the Siemens PET Biograph (TM) 6 scanner. This three-dimensional GATE model simulated 24336 LSO (Lutetium Oxyorthosilicate) detectors grouped into 144 blocks in accordance with the vendor's specifications. GATE results were compared with experimental data, obtained in accordance with the NEMA NU 2-2001 performance measurement protocol. The scatter phantom used by this protocol was also modelled within GATE, allowing us to simulate scatter fraction and count rate performance measurements. (c) 2006 Elsevier B.V. All rights reserved.
