A novel torso transceive surface coil array for prostate magnetic resonance imaging and spectroscopy at 4T is presented. It is shown that a conformal transceive surface coil array that uses 50&[Omega] transmitter amplifiers and receiver preamplifiers is capable of whole volume torso imaging while maintaining the high signal-to-noise ratio (SNR) inherent to surface coil designs. Through implementation of field focusing techniques, a 2-fold increase in SNR and improved homogeneity is shown in the prostate compared to a conventional circularly polarized driving scheme. This novel transceive surface coil array for volume imaging of the human torso at 4T is experimentally demonstrated.
