摘要
提出了基于Geant4的锥束CT成像系统的仿真技术,这样就能建立更真实还能够反映实际CT成像系统的仿真模型。仿真过程中不仅模拟了锥束射线的产生过程,建立了CT成像系统的几何模型,而且对投影成像过程进行了仿真研究。为了验证该仿真方法是否能够达到要求,将实际结果与仿真结果进行了详细的比较,经过多次数据对比结果表明,文中提出的CT系统仿真模型全面地考虑了CT成像过程中的所有物理过程,真实地显示了实际的CT成像,文中实验数据为CT成像系统的进一步研究提供了可靠依据。
The simulation technology of cone-beam CT imaging system based on Geant4 is built,simulation model more realistically reflects the actual CT imaging system can be built. The simulation process not only simulated the generation process of cone beam,established a geometric model of CT imaging system,and the projection imaging process was simulated. In order to verify the feasibility of this simulation method,the actual results and simulation results are compared. The results show that the CT simulation model takes that all physical processes in CT imaging process into account comprehensively,truelyreflects of the actual CT imaging system and provides a reliable basis for further study of CT imaging system.
