摘要
根据肺区的解剖形态特点，把肺区轮廓表示成为几段抛物线和直线的组合，在提取若干特征点的基础上，确定有关线段的参数，实现Ｘ光胸片的肺区自动识别，整个过程采用由粗到细，逐步求精的技术方法，计算量较小。本方法已经成功地应用于实际系统之中。
Based on the lung anatomy,the border of lung zone is expressed as a set of parabolic and straight lines.After several feature points are detected,the parameters of the lines are determined and the lung zone in X ray film is recognized.A coarse to fine strategy is employed in the procedure to lower the computation consuming.The method has been successfully used in an application system.
