定位放射線治療における品質管理サポートシステムの構築 Development of quality control support system for stereotactic radiation therapy 田邉, 悦章 タナベ, ヨシノリ 大倉, 保彦 オオクラ, ヤスヒコ 石田, 隆行 イシダ, タカユキ 定位放射線治療 画像処理 品質保証 品質管理 Stereotactic radio therapy (SRT) using a linear Accelerator (Linac) requires high precision in the table position and the center of irradiation. QC procedure is necessary To guarantee high precision of each SRT. As the QC procedure, we use the film shot method, in which the table correction width is derived from target images taken at various gantry angles and table angles. However, QC procedure is so complex that long time is wasted for this procedure. In addition, the degree of precision of QC procedure depends on each technologist. We developed a QC program support system to support QC procedure. This system processes images taken by the film shot method, and outputs the table correction width to adjust target position. For evaluation of our developed system, we compared correction width of obtained from our system with that from, conventional manual operation. Results showed that high degree of precision was achieved by employing our system. By using our system, one double check scheme, QC procedure by using both manual operation and our system, will be realized without any additional time for the procedure. 広島国際大学大学院総合人間科学研究科医療工学専攻 2007-03-15 jpn departmental bulletin paper VoR https://doi.org/10.60172/00000341 https://hirokoku-u.repo.nii.ac.jp/records/347 10.60172/00000341 AA12217173 1881-9265 医療工学雑誌 Journal of Medical Engineering 1 45 49 https://hirokoku-u.repo.nii.ac.jp/record/347/files/jme01_045.pdf application/pdf 524.8 kB 2023-03-11
