Segmentation of Juxtapleural Pulmonary Nodules Using a Robust Surface Estimate

Figure 11

Example of forward search algorithm showing the central slice of a nodule, with the top row of images displaying several different radii of the region excluded from the subset of pleural surface points, and the bottom row of images displaying the resulting segmentations. Radius 𝑟₂ contains the largest set of pleural surface points without including nodule surface points; including too many or too few points negatively affects the segmentation.
