Abstract

MRI guided cardiac interventional systems are configured to generate dynamic (interactive) visualizations of patient anatomy and medical devices during an MRI-guided procedure and may also include at least one user selectable 3-D volumetric (tissue characterization) map of target anatomy, e.g., a defined portion of the heart.

Description

[0001] related application [0002] This application claims U.S. Provisional Application Serial No. 61 / 185,072 filed June 8, 2009, U.S. Provisional Application Serial No. 61 / 187,323 filed June 16, 2009, Serial No. 61 / 187,323 filed June 16, 2009, The contents of U.S. Provisional Application No. 61 / 219,638 and priority of U.S. Provisional Application Serial No. 61 / 261,103, filed November 13, 2009, are hereby incorporated by reference as if in their entirety. technical field [0003] The present invention relates to MRI-guided systems, and may be particularly suitable for MRI-guided cardiac systems, such as EP systems for the treatment of atrial fibrillation (AFIB). Background technique [0004] Conventional cardiac EP (electrophysiology) systems are X-ray based systems that use electroanatomical maps. An electroanatomical map is a virtual representation of the heart showing sensed electrical activity. Examples of such systems include Carto® from Biosense Webster, Inc., Diamo...
