Paper Abstract
We developed a novel, powerful segmentation algorithm and an intuitive 3-D visualization tool for the examination of root fractures with minimum user intervention. The application computes and displays a suitable oblique orientation on a selected tooth by placing at least two splines (inside and outside of the tooth) in just one slice of the volume. Next, it allows the user to scroll through the volume, slice-by-slice in parallel to the plane, or to examine the tooth by changing the orientation of a 3-D object plane (called a virtual bitewing), which is placed, at the same time, in a volume rendition. Both the root canal and the root fracture are highlighted during the examination phase. Doctors (end users) are in control to quickly and confidently examine root fractures in 3-D, for any given oblique orientation, without worrying about missing a selected tooth. We have designed and implemented these algorithms using the image foresting transform (IFT) technique for interactive tooth segmentation and used a multi-scale parameter search for automatic oblique orientation estimation.
