We describe the design and the performance of an integrated RF Tx and Rx coil to enable highly accelerated ¹³C imaging of the human brain at 3T. This system combines a 31-channel receive array with integrated preamps and a high-power transmit coil in an improved mechanical design, overcoming several longstanding design challenges that previously limited hyperpolarized ¹³C imaging. The shorter imaging times and more uniform spatial coverage attainable with our design will lead to a substantially increase in the range of hyperpolarized imaging applications, and enable the transition to clinical use.
