MRI is playing an increasingly important role in the evaluation of cardiovascular disease. How to improve signal-to-noise rate (SNR) of cardiac imaging is one of the important factors for cardiovascular research. Usually Transmit/receive arrays are used in the 1.5T, 3T and 7T MRI for decreasing RF inhomogeneities and increasing SNR. Strengthening the effect of transmitting radio frequent(RF) can improve SNR under the ruled specific absorption rate(SAR). In this work, a novel shield circuit is proposed to strengthen transmitting magnetic field(B1) and we got much higher SNR from our experiment results.
