To maximize the imaging speed and SNR and ensure patient comfort, a coil system was designed for Hyperpolarized 3He human lung imaging. This system consisted an asymmetric quadrature birdcage coil as the transmit coil, and an 8-channel coil array as the receive coil. The asymmetric transmit coil used up the nearly entire bore volume with a profile calculated with conformal mapping. The receive coil was a modification of a proton Cardiac coil array to reduce the mechanic works and maximize the patient safety. This coil system was designed for the upgrading new GE MR750 system.
