Fusion of 2D x-ray images and 3D MRI datasets (XMRF) brings the MRI into the cath lab for online navigation and guidance during catheterization procedures. We present a new biplane method for XMRF using a prototype system and describe the accuracy of the resulting 2D roadmap (overlay) when rendered from an underlying, registered 3D MRI. We describe various visualization methods and demonstrate the clinical utility for complex congenital heart disease procedures.
