〔対象と方法〕検査者は大学生10 名とした．デジタルカメラで撮影した被写体は，89.0 度，89.5 度，90.0 度，90.5 度，91.0 度の5 条件を設定したモデルとした．得られたデジタル画像に対し，各条件で3 回の角度測定を行った．
〔結果〕すべての検査者において，測定値は，いずれの設定条件でも設定角度の大きい条件は小さい条件より大きかった．また，各条件間で有意な差を認めた．絶対誤差は，平均0.16 ± 0.05 度であった．級内相関係数ICC（1，3）は0.981-0.987 であった．
〔結語〕この研究では，デジタル画像解析が，大学生が測定しても，小さな変化を検出できる精度をもっていることが示唆された．, [Purpose] The purpose of this study is to verify the accuracy of angle measurement by digital image analysis for subjects set at 0.5-degree increments.
[Methods] The examiners were 10 university students. The subjects were photographed with a digital camera, and the model was set to five conditions: 89.0, 89.5, 90.0, 90.5, and 91.0 degrees. The examiner performed angle measurements in each condition using the digital images obtained.
[Results] In all examiners, measurements were greater for the larger set angle condition than for the smaller set angle condition for all conditions. In addition, measurements were significantly different between conditions. Absolute errors averaged 0.16 ± 0.05 degrees. The intraclass correlation coefficient ICC (1, 3) was 0.981-0.987.
[Conclusion] This study suggests that digital image analysis has the accuracy to detect small changes even when measured by university students., 研究論文, Original article},
