Segmentation of Juxtapleural Pulmonary Nodules Using a Robust Surface Estimate
Figure 13
Examples of nodule segmentation ratings, (a) the segmentation includes extensive nonnodule regions, (b) the segmentation does not include the entire nodule, (c) the segmentation stops slightly short of the wall, and (d) the segmentation includes all of the nodule but none of the wall. Segmentations with a rating of 3 or 4 were considered acceptable. The top image shows the grayscale region of interest, while the bottom image shows the segmentation, with the nodule indicated in white and high-intensity nonnodule structures indicated by gray. Images were all windowed to enhance visibility and are not to scale.
