- W2000733219 abstract "The bronchial tree is of direct clinical importance in the context of respective diseases, such as chronic obstructivepulmonary disease (COPD). It furthermore constitutes a reference structure for object localization in the lungs and itfinally provides access to lung tissue in, e.g., bronchoscope based procedures for diagnosis and therapy. This paperpresents a comprehensive anatomical model for the bronchial tree, including statistics of position, relative and absoluteorientation, length, and radius of 34 bronchial segments, going beyond previously published results. The model has beenbuilt from 16 manually annotated CT scans, covering several branching variants. The model is represented as acenterline/tree structure but can also be converted in a surface representation. Possible model applications are either toanatomically label extracted bronchial trees or to improve the tree extraction itself by identifying missing segments orsub-trees, e.g., if located beyond a bronchial stenosis. Bronchial tree labeling is achieved using a naive Bayesianclassifier based on the segment properties contained in the model in combination with tree matching. The tree matchingstep makes use of branching variations covered by the model. An evaluation of the model has been performed in a leaveone-out manner. In total, 87% of the branches resulting from preceding airway tree segmentation could be correctlylabeled. The individualized model enables the detection of missing branches, allowing a targeted search, e.g., a local rerunof the tree-segmentation segmentation." @default.
