| Outline of Final Research Achievements |
A range-compensating bolus is a key device to conform the irradiation field to the target boundary in carbon-ion therapy. We have developed a novel automated design method of the bolus by putting subscription doses in and around the target and OARs(Organs At Risk) and obtaining a bolus shape giving the optimum dose distribution by use of the least-square method. We have improved dose distribution in and around the target and OARs using the method. We have shown that dose in the OAR can be decreased significantly while keeping the dose uniformity in the target by using the bolus designed by the method.
