The use of dedicated RF coils can increase image SNR in magnetic resonance guided focused ultrasound (MRgFUS). However, shielding and eddy current effects of the ultrasound transducer ground plane (TGP) can significantly degrade the increased SNR. Accounting for these considerations when designing the ultrasound transducer can potentially increase SNR throughout the imaging volume during MRgFUS procedures.
