FaceSCAN3D - Photorealistic 3D Images for Medical Applications

Abstract

We present a technology for the creation of 3d-surface data of human faces. The radiation free technique enables the data acquisition in approx. 400 msec. The robust measurement principle uses the projection of sinusoidal fringe patterns to create three point clouds. The patented mirror setup allows to scan the patient easily from ear to ear. The data processing starts with the fully-automatic and accurate alignment of the three point clouds. Sophisticated pre-and post-processing algorithms enable then the creation of a curvature dependent thinned triangular mesh. Finally, a high-resolution 2d image is mapped to the mesh with sub-pixel accuracy to create a photo-realistic representation of the patient's face. Especially in a clinical environment the acceptance of new equipment depends strongly on the convenience of the handling of the device. The FaceSCAN 3D 's simple user interface makes this as easy as using a digital camera. Operating the scanner can be learned in less than 20 minutes. The data can be exported in a variety of formats suitable for importing into analysis software. The applications range from radiation-free cephalometrics to overlay with CBCT data. The FaceSCAN 3D data is an additional channel for the surgeon not only to do state-of-the art patient education but also gives him the possibility to plan his operations based on what we call a virtual patient model. An accurate before-after comparison enables quality control of the outcome of the surgery. In this paper the basics of our measurement principle are explained. After a short course about 3d data processing we focus on two interesting applications.
