| 内容記述 | At Heavy Ion Medical Accelerator in Chiba (HIMAC), more than 10,000 patients have been successfully treated by carbon ion beams since 1994. The successful results of treatments have led us to construct a new treatment facility equipped with a three-dimensional pencil beam scanning (PBS) irradiation system. After the construction of fixed beam lines, we started design and construction of a superconducting rotating gantry. The construction of rotating gantry was completed in September 2015. This gantry can provide the beam energy ranging from 50 to 430 MeV/u. Since the rotating gantry system requires that the beam profiles at the iso-center have no correlation between the rotation angles. We have confirmed the performance of the beam transport line with 10 gantry angles. The beam size deviation of each gantry angle are less than 10 percent of the desired value. The beam position was adjusted within 0.5 mm from mechanical isocenter for all gantry angle. We have started the commissioning of PBS system. Our PBS system is designed to treat moving target with fast rescanning as same as that of fixed beam line. In this presentation, we will report the present status of our gantry and related beam tests and initial clinical result. | |||||
