MR guided vascular interventions require reliable and safe catheter tracking methods. Direct currents produce susceptibility artefacts in MRI which can be adjusted dependent on the current applied. In this study a high frequency safe method of direct current based catheter tracking in interventional MRI is presented ready to be introduced in clinical routine. It is based on a miniaturized optoelectric circuit allowing building a vascular catheters prototype which diameter does not exceed 7F.
