| Outline of Final Research Achievements |
We achieved a high accuracy and high speed of dose calculation for proton beam therapy. In order to evaluate body motion, performance of 4-dimensional CT was evaluated, and we examined operation method of the 4-dimensional CT. With the aim of high-precision in-vivo proton dosimetry, in-vivo dosimetry was performed by using a 4-dimensional position sensor and a MOSFET detector. We could successfully control the uncertainty of the measurement position by using the 4-dimensional position sensor within 1 mm for in-vivo proton dosimetry.
