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.
