Catheter exploration, key procedure for cardiac
arrhythmia diagnosis and treatment, could benefit from
MRI guidance and procedure monitoring. In this work, we
present a homemade MR compatible 3D and real-time
catheter navigation device based on electric field
detection. The system was validated in vitro providing
catheter positions with a maximum error of 5.5 mm at 25
frames per second. In vivo feasibility was also
demonstrated in a swine model. Such work opens
perspectives for catheter guidance and 3D slice tracking
during MR exam enabling real-time visualization of the
targeted area and respiratory motion correction.
