The travelling wave approach to MRI uses an antenna to propagate a TW through the bore of a 7T+ scanner. Using a waveguide to match the incident wave into the head a stronger B1+ can be generated. This has been simulated and assessed using SEMCAD X. This design is compatible with the use of local receive coils and local shim coils. This work indicates that this setup is capable of generating B1+ in the head with increased efficiency compared to normal TW methods. Multiple modes can be generated allowing for a multi-transmit approach to improve B1+ homogeneity across the brain.
