| 研究実績の概要 |
A spread-out Bragg peak (SOBP) of 3 cm was produced for a C-12 beam (350 MeV/u) using a designed range modulator in the carbon therapy facility of the Heavy Ion Medical Accelerator in Chiba (HIMAC). Dose and PET data for C-12 beams with several energies for a PMMA phantom were prepared using Monte Carlo simulation (Phits code). The algorithm for converting PET data to dose distribution and its optimization are still under development.

2: おおむね順調に進展している
理由
The progress of the research was almost according to the original plan and there was no problem by now.
|
| 今後の研究の推進方策 |
For the next fiscal year, a head and neck phantom will be simulated and experimentally irradiated with both C-11 and C-12 beams (pristine Bragg peak and SOBP) in the HIMAC. The optimization of the algorithm for dose estimation using PET data for both C-11 and C-12 beams will be performed for the head and neck phantom.
