A MRI-based platform for catheter navigation.

The development of minimally invasive surgical techniques using magnetism is expanding. Our research group is exploring catheter steering using the gradient field of a modified clinical Magnetic Resonance Imaging (MRI) system. This paper focuses on the upgrade of the MRI testing platform towards an integrated system allowing for in vitro and in vivo experiments. The expected steering capabilities of the platform are evaluated through experimental tests, and catheter tracking is adapted accordingly while being tested for potential medical interventions.
