Dose Calculation of Radiotherapy Based on DPM

Objective:3D treatment planning systems in radiotherapy is important to achieve an accurate assessment of all aspects of the dose distribution and requires visualization of dose distribution in an easy and clear way.Method(dose planning method,DPM) based on Monte Carlo method was rewrited to calculate dose and extend its functionality.Primly realized DPM modeling,conversion into DPM input files and disposing dose calculation results in 2D and 3D display.Results DPM modified can not only deal with geometry medium but also dispose of CT data and get dose calculation visualization results.The simulation results have shown that this method is correct and effective.Conclusion The proposed method is capable of enhancing the level of radiotherapy planning.
