Abstract

A system (100) and method (205-265) for performing a virtual endoscopy is provided. The method (205-265) comprises the steps of: calculating a distance map using three-dimensional (3D) data of a lumen (210); calculating a multiplanar reconstruction (MPR) of the lumen (220), wherein the MPR is calculated orthogonal to the lumen at an endoscope position; performing a first region growing on the MPR of the lumen at the endoscope position (225), wherein data associated with the first region is marked (230); calculating a minimum distance and a maximum distance from the marked data of the first region growing using corresponding distances from the distance map (240); performing a second region growing on the MPR of the lumen for data outside the first region growing (245), wherein data associated with the second region is marked (250); and performing a 3D rendering of the marked data associated with the first region growing and the second region growing (260).
