Abstract:
1. A method for segmenting a three-dimensional (3D) image dataset, said method comprising: accessing a 3D image dataset that includes a plurality of image slices; segmenting an object of interest in the 3D image dataset; generating an initial 3D mesh corresponding to the segmented object of interest; displaying a 3D image of the segmented object of interest and the initial 3D mesh on a display device, wherein the initial 3D mesh is displayed overlaid on the segmented object of interest; receiving a user input to select at least one end point on the 3D image that is not on the initial 3D mesh; and adjusting the initial 3D mesh to provide an adjusted 3D mesh based on the selected end point, wherein the adjusting includes identifying a closest vertex on the initial 3D mesh to the selected end point, automatically identifying an update area including the closest vertex, calculating a corresponding adjustment distance for each vertex in the update area, and adjusting each vertex in the update area using the corresponding adjustment distances, wherein the user input includes only a single click from the user, wherein the adjustment distances for the vertices are determined based on a distance from the selected end point to the closest vertex, and wherein the adjusted 3D mesh is automatically extended to the selected end point.
