| 内容記述 | The QA team of Japan Carbon-ion Radiation Oncology Study Group (J-CROS), composed of the medical physicists of carbon-ion radiotherapy centers, has conducted several QA activities such as dose inter-comparison and on-site dose audit (end-to-end test) to assure and improve the quality of multi-center clinical trial of carbon-ion radiotherapy in Japan. Through these interactional activities among medical physicists of each center, it was recognized that there were some variations in practical procedures for treatment planning and beam delivery processes. We decided to make survey for the procedures of respiratory gating and metal artifact management in treatment planning process as those were considered to have big effect on the carbon-ion radiotherapy. For the respiratory gating procedure, 17 items were surveyed such as internal/external gating, type of sensor, delayed time commissioning, methodology of CT acquisition, how to decide the gate level, how to manage with respiratory level drift during treatment, QA and so on. For the metal artifact management for treatment planning process, 12 items were surveyed such as calculation methods for the beam penetrating metal including replacement of stopping power ratio value and evaluation of its volume, how to manage streak artifacts or contrast materials and so on. The results were shared with the QA team of J-CROS to standardize and improve the methodology of each center. | |||||
