| Outline of Final Research Achievements |
We developed a web-based CT dosimetry system, WAZA-ARIv2. To enable the dose calculation for a wider range of subjects, WAZA-ARIv2 utilizes voxelized non-uniform rational B-spline (NURBS)-based phantoms developed by Florida University (0, 1, 5, 10 and 15 years child, both sexes) in addition to the JAEA voxel phantoms of the average-sized Japanese male and female. It is also capable of calculating doses to adults with small, large and extra-large body sizes. The system computes tissue doses on user’s request referring to the dose coefficient datasets that have been calculated using the Particle and Heavy Ion Transport code System (PHITS). As the phantoms used represent physiques of Asian population, WAZA-ARIv2 is appropriate to calculate patient doses in Asian countries.
