Research Abstract

This research project aims to develop new image registration techniques for next-generation computer-assisted surgery and intervention system based on medical images. We develop a novel image registration technique that considers variations of organ deformation and movement. In this research project we collected fundamental data for enabling us to develop new image registration techniques that consider organ deformation and movement Also we applied new image registration techniques to medical image segmentation process. The segmentation results are utilized for computer-assisted surgery and intervention.
