title: Image thickness correction for navigation with 3D intra-cardiac ultrasound catheter.
abstract: In this paper we present an algorithm to correct 3D reconstruction errors of 3D ultrasound catheter caused by ultrasound image thickness. We also provide a method to quickly measure ultrasound image plane's thickness. With thickness correction registration accuracy of navigation system using 3D ultrasound catheters can be improved by 20%.
