放射線の照射量を 3 次元的に測定することを目指し、ゲル線量計用の光学 CT 装置の開発を行っている。本研究では、性能評価の 1 つである MTF を調べた。また試料を水中で測定することも検討されているが、水中での測定では像が拡大し歪むことがわかった。このため、最初にこの影響と補正方法について検討をおこなった。その結果、水中での測定では拡大率は画像の中心で 130% であった。歪み率は画像中心から 5 cm の場所で 15%であった。この歪みは、OpenCV を用いて補正することが可能であ...

放射線の照射量を3次元的に測定することを目指し、ゲル線量計用の光CTの試作を行った。ゲル線量計は、放射線を吸収した部分が白濁化する性質を持っており、吸収線量が多いほど、より濃く白濁化する。白濁化の範囲と量が分かれば吸収線量を三次元的に推定できる。そこで、本研究でゲル線量計の白濁化の範囲と量を測定するための安価な光学 CT 装置を試作した。試作した光学 CT 装置は、試料を回転させる駆動系、試料を撮影するための光源とカメラ、これらを制御するシングルボードコンピュータなどで構成されている。本装...
