Abstract:
This paper reviewed the dose calculation method for treatment planning system of multi-source stereotactic radiotherapy system with Gamma beam, and presented a fast method based on cone coordinate system and multi-core parallelization. The experiments show that the new method not only ensures the accuracy of dose calculation, but also greatly improves the speed, which can reach as 20 times as that of traditional method.
