The study and implementation of dose calculation method in OUR-Body Gamma Knife

Radiation dose in the importance of radiation therapy is well known, with the advancement and development of technology, Radiation therapy in cancer treatment plays an important role. The current radiation treatment planning system using empirical or semi experienced conventional dose algorithm, the calculated dose distribution is not precise enough. Based on OUR-Body Gamma Knife radiation treatment planning software system, this article proposes dose calculation optimization method to meet the computing requirements of the premise and reduce dose points which need to calculate as much as possible, to improve the calculation speed. According to the experimental results demonstrate the feasibility of the optimization algorithm, and finally complete visualization of dose distribution.
