Accelerating Virtual Surgery Simulation for Congenital Aural Atresia

摘要

In this paper, we proposed a new efficient implementation for simulation of surgery planning for congenital aural atresia. We first applied a 2-level image segmentation schema to classify the inner ear structures. Based on it, several 3D texture volumes were generated and sent to graphical pipeline on a PC platform. By exploiting the texturing-mapping capability on the PC graphics/video board, a 3D image was created with high quality showing the accurate spatial relationships of the complex surgical anatomy of congenitally atretic ears. Furthermore, we exploited the graphics hardware-supported per-fragment function to perform the geometric clipping on 3D volume data to interactively simulate the procedure of surgical operation. The result was very encouraging.
