X-ray Based Craniofacial Visualization and Surgery Simulation
نویسندگان
چکیده
This paper presents a novel craniofacial visualization technique with the developments from both computer vision and graphics. It is a low radiation, low cost alternative to CT-based system for the reconstruction of 3D cranium using only three X-rays. We paste lead markers on the subject’s face which allow a 3D face model to be constructed by correlated vision. Then the surface of the cranium is obtained by subtracting soft tissue depth from face surface. We also present a new algorithm to solve the matching by evolutionary programming and designed a supervised learning method to estimate the soft tissue stiffness parameters.

Augmented Reality (AR) techniques can be applied in medicine to help physicians in diagnosis, treatment planning, surgery simulation, among others. In craniofacial treatments, it can also be used to support prediction in patient’s own body. In this context, AR applications should fill more requirements than usual, like markerless support, tracking deformable objects and volume rendering. This p...
