Currently, the conventional empirical or semi-empirical dose calculation algorithms for radiation treatment planning system have been selected as dose engines. The accuracy of these dose calculation algorithms is limited. The main problem is that they fail to adequately consider the lateral transport of radiation or loss of electronic equilibrium near(More)
The decrease of accuracy in patients' repeated positioning in radiotherapy due to body's transformation is considered and a positioning error measurement method using dynamic template matching technique is brought forward in this paper. This method is an improvement of the matching method to correct positioning error based on the CT digitally reconstructed(More)
