Synopsis

Keywords: Non-Array RF Coils, Antennas & Waveguides, RF Arrays & SystemsWe show that novel modifications to a mock Transcranial MR-guided Focused Ultrasound (TMRgFUS) system show potential to greatly improve MR performance. By using a transfer medium with reduced electric permittivity combined with slots in the transducer array ground plane we measure a 2-3 fold increase in SNR across the middle of a head-phantom portion of a mock TMRgFUS system.
