| 摘 要： | 提出一种交互式的肺实质分割算法,该算法充分利用序列CT图像相邻层中肺实质轮廓变化缓慢的特点,结合且改进了Live-Wire模型、Snake模型以及轮廓插值方法.并辅以操作人员的专业知识.首先人工的在序列CT图像中选取肺实质的关键层,然后通过Live-Wire模型交互式的勾勒其轮廓,再进行轮廓插值得到其他层肺实质的初始轮廓,最后通过Snake模型演化得到所有层的肺实质准确分割结果,并加以手工修正.实验结果表明,该算法能快速准确的从序列CT图像中分割出肺实质.

| Abstract: | In this paper,an interactive lung parenchyma segmentation algorithm is put forward with improved Live-Wire model,Snake model and contour interpolation,which takes full advantage of lung contours'slow change in adjacent CT images layer and operators'professional knowledge.First,we manually select key slices of lung parenchyma in serial CT images,then draw the lung's contours in key slices by Live-Wire model,get the lung's contours in other slices by contour interpolation,finally segment lung's accurate conto... |
