Abstract: In an example, a graphical user interface can be used to display a graphical representation of a virtual reference structure for an anatomic structure, the reference structure being determined from geometry of the anatomic structure. A location parameter along the reference structure is determined in response to a first user input from a user input device. A graphical proxy marker is displayed on the graphical representation of the reference structure based on the location parameter. A fixed location is selected along the reference structure for a final graphical marker in response to a second user input from the from the user input device. An output visualization is generated to include at least one view of the anatomic structure and a graphical representation of the final graphical marker at the fixed location.

Abstract: In an example, a method includes selecting a user-selected seed voxel from a medical image. The user-selected seed voxel is shifted to an adjusted seed voxel in an evaluation region based on an evaluation. The evaluation region includes the user-selected seed voxel and at least one other voxel within a predetermined spatial distance. A given region in the image volume is filled with voxels to provide a segmented volume for the given region based on the adjusted seed voxel and segmentation filter parameters. A segmentation region is evaluated to ascertain a quality of the fill. Seed candidates may be determined from a set of the filled voxels adjacent a boundary of the for another region given region in response to determining that the quality of the fill indicates a valid segmentation for the anatomic vessel structure in the given region. Segmented vessel image data is stored.
