From: Computational modeling of the obstructive lung diseases asthma and COPD
Combined image-processing and modeling results from a CT scan of a patient with COPD from the Synergy-COPD project. Segmentation of (A) central airways and (B) segments (calculated using both image processing and modeling approaches, color coded by segment). (C) Displays emphysematous regions (emphysema indicated in white and normal tissue in brown) extracted using thresholding of the image intensity values (emphysema <950 HU) [Doel, 2014, unpublished results].
