| 研究実績の概要 |
A library of dose data and PET data for C-11 beams with energies of 170, 210, 290 and 350 MeV/u for a PMMA phantom was made using Monte Carlo simulation (Phits code). The algorithm for converting PET data to dose distribution was constructed and its optimization is still under development. A ridge filter for a C-11 beam (350 MeV) with 2 centimeter of SOBP was designed and tested experimentally in the carbon therapy facility of the Heavy Ion Medical Accelerator in Chiba (HIMAC).

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 ridge filter for C-12 beam with 2~3 cm SOBP will be designed and its performance will be optimized experimentally in the HIMAC. Meanwhile, optimization of the algorithm for dose estimation using PET data for both C-11 and C-12 beams will be continued for a PMMA phantom.
