値の精度を，電離箱線量計を用いた実測データとの対比を含めて検討した．\n　レイトレーシング法による照射野面積の算出精度はクラークソン法による結果と比較して有意に優れていた．MU 値\nは照射野形状によっては一部実測データと一致しなかった．その改善にはコリメータからの透過線量や被照射体の不均質補正を演算するプロセス追加が大きな役割を果たすと思われる．","subitem_description_type":"Abstract"}]},"item_3_description_7":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"弘前医学.
