Outline of Final Research Achievements

Immobilizaion during radiotherapy is an essential component for highly precise radiotherapy. However, the standard fixation devise used in adulthood is hard to be applied for childhood. We conducted this researh to develop new head immobilization method for pediatric patients who are reluctant to be introduced tight plastic mask covering face. This new technique consists of customized head support and high-speed precise motion measurement system. We had improved in method to make customized head support. High-speed precise motion measurement was achieved by continuous surface data collection, avoiding X-ray exposure. Two experimental model of motion measurement system were made. Before implementing this system to bed side and clinical evaluation, the acceptance of machine among childhood needs to be improved. New patent for this motinon measurement system is under consideration.
