XVL for medicine: the web-based medical 3D applications

We are researching on a new framework for transfering 3D medical model data through the Internet. The eXtented Vrml with Lattice (XVL) is one of the effective ways because of its file size and its programmable feature. To estimate the effectiveness of XVL, we have evaluated the volumetric error between the original models and XVL models. We also made several web-based medical applications such as a textbook for the cleft lip repair surgery, an observing tool for mandibular movement, and CT/MR image browsing tool. The model quality evaluation and the applications show the advantages of XVL for medical use.
