A Travelling Wave Antenna with Matched Waveguide for Head Imaging at 7 T

Daniel James Lee¹, Paul M. Glover¹

The travelling wave approach to MRI uses an antenna to propagate a TW through the bore of a 7T+ scanner. A novel design where the antenna is incorporated into a dielectric waveguide which then matches the incident wave into the head is presented. Such a set up has been constructed and tested in vivo.
