Outline of Final Research Achievements

For the dynamic 3D rotational irradiation, software having functions to acquire positional parameters of irradiation devices and the treatment couch from the system was implemented. In addition, we devised an algorithm to determine irradiation route from cumulative dose distribution along it. From the 2D map based on the polar coordinates in which the irradiation position of the irradiation radiation from each of the organs created by 3D model and the irradiation position from the radiation source are plotted along the abscissa and the latitude as the ordinate, a risk map indicating the degree of risk of each organ and a search map were generated. It has been observed that the obtained irradiation route works well as expected on the simulator. In addition, we posted paper on each subject regarding quantitative consideration on image quality and exposure dose in the target treatment device and gold marker detection algorithm with high robustness.
