Synopsis

The development of RF coils for the ultrahigh-field(UHF) MRI system is greatly significant for biomedical research as it determines imaging performance. In this work，an 8-channel transceiver array was designed and constructed for UHF MRI at 9.4 T to take full advantage of the benefits provided by higher field strengths. The phantom and in vivo studies were performed on preclinical 9.4 T MRI system to verify the proposed tansceiver performance. The results proved the ability of the proposed 8-channel transceiver array to obtain high signal-to-noise ratio (SNR) and high-spatial resolution MR images at 9.4T and indicated the potentiality for UHF MRIapplications.
