The purpose of the project was to develop a fast and accurate dose calculation code for the state-of-the-art radiotherapy of cancer and a treatment planning optimization system based on it. While we could not complete the development of the dose calculation code, we revealed the necessary conditions which should be satisfied by the new dose calculation code by investigating small fields, where the uncertainty of usual dose calculation methods can be large. As for the optimization for treatment planning, we developed the method of the evaluation of dose uncertainty, which is necessary for the minimization of dose uncertainty. We also developed the dose calculation method for moving tumors, which can be used for the optimization considering tumor motions.
