 note = {application/pdf, 論文(Article), これまで,著者らは,CTやレーザースキャンなどのデータから骨の3次元モデルを作成し,2方向X線画像を用いた下肢アライメント解析と組み合わせた評価,2方向X線画像と6自由度電気角度計を用いた膝関節運動測定などを行うシステムの開発をしてきた。また,これらのシステムを応用して人工膝関節の設置評価や,人工膝関節設置法の開発をしてきた。下肢アライメント解析は,従来の2方向X線撮影による解析に骨の3次元モデルと骨形状から決めた参照点で定義する解剖学的座標系を導入することで臨床評価パラメターを3次元的に定義できることを述べている。また,6自由度電気角度計を用いた膝関節運動測定について述べている。この機器は,歩行中の膝関節運動の測定にも用いることができ,その測定結果を示している。人工膝関節の設置評価では,2方向X線撮影したX線画像上に射影行列を用いて人工関節コンポーネントモデルを投影し,位置と姿勢を評価する方法を述べた。人工膝関節設置法の開発では,6軸の特殊ディバイスを用いて骨切りガイドの位置と姿勢を変化させ,術前に3次元骨モデルを用いて決めた目標位置に,人工関節の大腿骨コンポーネントを移動させる方法を述べた。, We made a three dimensional skeletal model of leg using the bone contour data from CT and non-contact three dimensional digitizer and developed evaluation system combining this scanning and the analysis of leg alignment-assessment based on two directional X ray imaging (bi-planar X-rays). Further, we have engaged on the development of measuring system of knee joint movement using bi-planar X-rays and six-degree-of freedom electric goniometer. Also we carried out the evaluation of installation of artificial knee joint and the methods of installation. We have described that analysis of leg alignment assessment can be determined the clinical evaluation parameter into three dimensions by incorporating the anatomical coordinate systems which are defined the reference points obtained from traditional two directional X ray photographical analysis, three dimensional model of bones and shapes of bones. We have described the measurement of movement of knee joints using six-degree-of-freedom electric goniometer. This equipment can be employed for measurement of movement of knee joint during walking and the some results are presented. In the evaluation of installment we have described the method of evaluation from both position and statue by projecting the artificial joint component models using projective determinants from X ray images photographed from two directions. In development of installation techniques of artificial knee joints, we have altered the position and statue of the guide for bone cutting, using a special device with six axis and transfer the femoral bone components to the target position determined by 3 dimensional model of bones before an operation.},
