Monte Carlo Method and 3D Digital Human Model Applied for Quality Assurance of the Radiotherapy Treatment Planning
蒙特卡罗方法和三维数字人体模型在放疗计划质量保证中的应用

Quality assurance in the radiotherapy planning is an effective method to assure the success of radiotherapy. Some methods validating and evaluating radiotherapy planning, such as the CT simulator and phantom method, have their own advantages and disadvantages. A method based upon human image data is proposed to design the simulation model. The Monte Carlo software MCNP and the Visible Human Project (VHP) dataset are used to simulate the 3-D dose distribution in human body during the procedure of radiotherapy. This method can obtain the real 3-D dose distribution in radiotherapy because of the use of human real image data and the accuracy of Monte Carlo method in computing the particle transportation.
