Segmentation of Pulmonary Vascular Trees from Thoracic 3D CT Images

Figure 8

Two examples of segmentation results. (a) and (c) are the results from a TLC scan. (b) and (d) are from the associated FRC scan of the same subject. All images are shown at the same scale. Note the breathing-related changes of lung vasculature caused by regional lung parenchymal expansion between the TLC and FRC lung volumes.
