Abstract

We developed a magnetic resonance (MR)-safe tracking catheter using an optical fiber with a light-diffusing tip segment to transport laser energy through the catheter. This energy is converted to a DC current running througha small coil at the catheter tip. Our method is inherently MR-safe since the use of long conducting wires is avoided. The intravoxel dephasing Induced by the tip coil was clearly visible for laser powers between 250 mW and 750 mW for all angular positions of the catheter. (C) 2001 Wiley-Liss, Inc.
