The Application of CT Simulation in Proton Therapy

摘要: 先进的计算机技术及软件设计使虚模拟(Virtualsimulation,VSIM)这一最早由GeorgeSherouse提出的技术得以实现。VSIM主要是利用医学影像数据创建三维虚拟病人模型并将之应用于肿瘤放射治疗的设计和实施。以CT图像为基础的照射模拟已经成为当代放射治疗中VSIM应用的主要方法。质子治疗的高精度要求更加凸显CT模拟技术的重要性。本文结合质子治疗实际工作阐明CT模拟的过程和方法并讨论其优越性和缺点。

Abstract: Advances in computer technology and software design have enabled the concept of Virtual Simulation (VSIM), first suggested by George Sherouse, to be realized. VSIM is a technique involving the use of medical image data to construct a 3D virtual patient model which is used for the design and implement of radiation treatment. CT-based virtual simulation, the so-called CT Simulation (CTSIM) has become an integral part of the application of VSIM in modern radiotherapy. High precision of proton therapy made this technique even more prominent. The procedures and the whole process of simulation used in our proton center were described, the advantages as well as disadvantages of this technique were also discussed.
