Lung Segmentation in 4D CT Volumes Based on Robust Active Shape Model Matching

Figure 2

Illustration of intermediate and final results of the proposed 4D lung segmentation approach. (a) 4D CT data consisting of a TLC and FRC lung scan pair to be segmented. (b) Model initialization. (c-d) 4D RASM segmentation with (c) mutual segmentations and (d) result after the constrained adaptation step. (e) 4D OSF segmentation result.
