evelopment and Verification of a Monte Carlo Dose Calculation Program MagicDose for Boron Neutron Capture Therapy
ose calculation is the foundation of Boron Neutron Capture Therapy (BNCT). MagicDose, a dose calcula- tion program for the BNCT treatment planning system, is developed based on the Monte Carlo method. Firstly, the voxel phantom of the modified Snyder head with 16, 8 mm are constructed, and the deviation of each result on y=x and the calculation time are statistical.The modified Snyder head phantom with tumor at three different spatial resolutions of 16, 8, and 1 mm are constructed, and the depth-dose-rate curves and spatial distribution maps are analyzed. Finally, the patient's head CT data is used as an application. The results show that the results calculated by MagicDose and MCNP are in good consistency, demonstrating that the computational efficiency of MagicDose is also better than that of MCNP. As the spatial resolution increases, the variability of the dose rate results is smaller. The voxel size and the number of threads are both inversely proportional to the time. For the CT model, the voxel phantom is successfully constructed and the calculation results are reasonable. The above results verify the correctness of MagicDose, which also provides a reference for optimizing the design of the voxel phantom in clinical treatment.
