Lung Segmentation by Cascade Registration

- Cascade registration allows segmenting the lungs in a sequence of ARDS images.
- Lung motion masks for all images are obtained by registration from one initial mask.
- The method deforms the lung segmentation from high-contrast to low-contrast images.
- Self-atlas segmentation method performed better than interactive segmentation.
- The method achieved a Dice score of 96.5% with respect to expert-traced contours.
