摘要： An intuitive user interface is provided for endoscopic view visualization. The user interface may permit individual or simultaneous navigation through images displayed in an endoscopic view window, a three dimensional overview window, and a multi-planar reformatted window. An operation performed directly on one of the windows may commence the navigation. The endoscopic view window may be divided into a plurality of sub-regions, each sub-region having a corresponding navigation function. The endoscopic view window and the three dimensional overview window may have corresponding icons related to a single location in corresponding images being displayed. The corresponding icons may be color coded to facilitate intuitive alignment of the corresponding images displayed in the different windows. The three dimensional overview window may have a geometric icon to facilitate intuitive alignment of the corresponding images. The multi-planar reformatted window may permit spherical navigation through the images displayed.

摘要： A computer-implemented method is disclosed for comparing three dimensional (3D) digital medical images. The method uses a reference MPR to position subsequent MPRs in one or more other 3D digital medical images so their content matches the reference MPR. The matched MPRs may then be used by a medical professional to diagnose a patient condition. The ability to quickly and automatically position matching MPRs for multiple 3D images eases the medical staff workload and shortens diagnostics time. Matching MPRs provides an effective way to view the 3D volumes for anatomical changes over time and to monitor medical conditions such as stenosis and tumors.

摘要： A segmentation of the esophagus from image data by specifying only the two end points is disclosed. Surrounding structures are used as high-level constraints to construct shape and appearance models. Prior shape information is integrated for the segmentation of a new esophagus using a Bayesian formulation. This permits to automatically select the proper models. Given the end points, a shortest path algorithm provides the optimal esophagus according to the Bayesian formulation.
