Research and Implementation of Cone Beam 3D CT Simulation System
锥束三维CT仿真系统的研究与实现*

Cone beam 3D CT system comes into being the present research hotspot of CT technique. This paper does related research on cone beam 3D CT simulation technique: establishes the mathematical model of simulation system using Monte Carlo method; proposes a simulation algorithm based on ray-tracing and on the X-ray attenuation law; develops a simulation prototype software successfully, which is tested and verified by using hollow turbine blade CAD model as phantom object.
