Robotic catheter system for mri-guided cardiovascular interventions

MRI-guided robotics offers possibility for physicians to perform interventions remotely on confined anatomy. While the pathological and physiological changes could be visualized by high-contrast volumetric MRI scan during the procedure, robots promise improved navigation with added dexterity and precision.
