"Virtual Touch": An Efficient Registration Method for Catheter Navigation in Left Atrium

In this paper, we present a left atrium registration system which utilizes a 3D intra-cardiac ultrasound catheter for faster (more than 700 times) and higher quality surface registration point collection than current systems and eventually improves the registration accuracy and stability. With better registration our a system can greatly improve the ablation catheter navigation system which is being used in many hospitals to guide left atrium endocardium ablation procedure.
