摘要： This invention relates generally to medical imaging and, in particular, to a method and system for I) reconstructing a model path through a branched tubular organ, II) automatic lymph node station mapping, and III) automatic path or route report generation. Novel methodologies and systems segment and define accurate endoluminal surfaces in airway trees, including small peripheral bronchi. An automatic algorithm is described that searches the entire lung volume for airway branches and poses airway-tree segmentation as a global graph-theoretic optimization problem. A suite of interactive segmentation tools for cleaning and extending critical areas of the automatically segmented result is disclosed. A model path is reconstructed through the airway tree. Additionally, a computer-based system for automatically locating the central chest lymph -node stations in a 3D MDCT image is described. Automated analysis methods extract the airway tree, airway-tree centerlines, aorta, pulmonary artery, lungs, key skeletal structures, and major-airway labels. Geometrical and anatomical cues arising from the extracted structures are used to localize the major nodal stations. The system calculates and displays the nodal stations in 3D. Visualization tools within the system enable the user to interact with the stations to locate visible lymph nodes. Additionally, a method and apparatus for producing and previewing a report for peripheral bronchoscopic procedures using patient-specific MDCT chest scans is disclosed. The report provides quantitative data about the route and both static and dynamic previews of the procedure. Static previews consist of virtual bronchoscopic endoluminal renderings at bifurcations encountered along the route, renderings of the airway tree and ROI at the suggested biopsy location, and three-dimensional cues as to the location for the biopsy.
