| 摘 要： | 结合二值形态学原理,对人体胸腔横截面的CT图像通过标记、搜索连通域等处理,提取胸腔的轮廓和肺及食管的轮廓。将处理图像复原与原图像进行对比表明,本文所采用的方法能准确地提取人体胸腔和肺及食管的轮廓,误差小于人眼的辨别能力。

| Abstract: | A method is presented in this paper which processes the human chest CT image with binary morphology theory,then marks and searches each connected domain to find chest contour and boundaries of lung and esophagus.Comparing with original CT image,the extracted boundaries have sufficient accuracy and human eyes cannot distinguish the error. |
