我们的目的是评估的识别性能，使用生物指纹提取平均胸片和模板匹配技术，以防止左右翻转错误。我们通过对100张后前位胸片进行平均，得出了每种性别的平均胸片。此外，在一致性和验证测试中分别使用了400和566张胸片，并在假设发生左右翻转错误的情况下将其水平翻转以生成翻转胸片。计算胸片与翻转胸片的相关值。当我们使用从除肺尖之外的四个生物指纹的相关值计算的相关指数时，在一致性和验证性测试中分别正确识别了96.5%（386/400）和95.8%（542/566）的左侧或右侧。这一结果表明，我们提出的方法将是有前途的防止左右翻转错误。
We aimed to evaluate the identification performance achieved using biological fingerprints extracted from averaged chest radiographs and template-matching techniques for the prevention of left–right flipping mistakes. We produced averaged chest radiographs for each sex by averaging 100 posteroanterior chest radiographs. Further, 400 and 566 chest radiographs were used in consistency and validation tests, respectively, and they were flipped horizontally to produce flipped chest radiographs under the assumption that the left–right flipping mistake occurred. The correlation values obtained with chest radiographs and those obtained with flipped chest radiographs were calculated. When we used correlation indices calculated from the correlation values from four biological fingerprints except for the lung apex, 96.5% (386/400) and 95.8% (542/566) of the left or right sides were identified correctly in the consistency and validation tests, respectively. This result indicates that our proposed method would be promising for the prevention of left–right flipping mistakes.
