Abstract

The exact localization of signal recording probes or deep stimulation probes by magnetic resonance imaging (MRI) has significant importance in studying and understanding how the brain functions. But the magnetic susceptibility of the probes itself distorts the MRI image and creates error in position measurement. In this paper we propose an MRI compatible flexible probe with magnetic susceptibility that is well matched with the brain tissue. The well-matched magnetic susceptibility of the probe enables high resolution structural and functional MRI even at ultra-high Bfield strengths. The MRI images shows almost zero artifacts around the implanted probe in the phantom tissue.
