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 image layers and operators' professional knowledge. Firstly, 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 contours in all slices by Snake model and manual modification. Experiments showed that this algorithm can segment lung parenchyma in serial CT images quickly and accurately.
