Outline of Final Research Achievements

Recent advancement of radiation therapy irradiation technique has enabled us to concentrate more radiation dose to malignant tumors and spare exposure to surrounding normal tissues simultaneously than before. The advancement of radiation therapy has induced the complication of treatment plans, which makes the evaluation of the quality of them difficult, and the increase of the time cost of making them. The purposes of this study are the developments of the quality evaluation criteria for treatment plans and automatic treatment planning algorithms referring them for high-precision radiotherapy.
We developed the semi-automatic treatment planning algorithms for high-precision whole-breast irradiation techniques. The quality evaluation criteria we adopted turned to take much time to calculate than expected and, therefore, we could not implement them into the automatic treatment planning algorithms.
