Outline of Final Research Achievements

In this study, we investigated the optimal imaging conditions in order to reduce patient exposure dose while ensuring high position accuracy in image-guided radiotherapy (IGRT). As a result of applying this condition for patients who received radiation therapy for the head region, the exposure dose could be reduced to less than 0.50 mGy while ensuring the positional accuracy of 1 mm. We also evaluated the exposure dose during fluoroscopy in real-time tumor-tracking radiotherapy for lung cancer, and showed that the entrance skin dose can be reduced to less than 100 mGy by setting the gating window to 4 mm.

Academic Significance and Societal Importance of the Research Achievements

本研究は、画像誘導放射線治療における位置合わせ精度と被ばく線量の相反する2つの因子を考慮して最適なX線撮像条件を検討した初めての研究である。実際に頭部放射線治療を受けた患者の位置合わせにおいて、本研究によって検討した撮像条件を適応した結果、位置合わせ精度が低下することなく、患者被ばく線量を低減できたことから、患者への恩恵は計り知れず、その社会的意義は大きい。本研究によって得られた成果は、画像誘導放射線治療における被ばく線量管理を展開するための基盤の確立に寄与する。
