We have successfully constructed a novel 8-channel phase-array transmit/receive head coil on Siemens 3T Tim Trio system for research on parallel transmission techniques including multiple-channel phase-array RF coil design and homogenous B1 shimming. The coil was better suited for Asian people fMRI studies, with an unblocked visual field as well as high image SNR and signal stability. The whole setup including the Tx/Rx coil, the related RF interface and parallel transmission techniques would further be applied to a Siemens 7T system and is expected to achieve good anatomical and functional images in ultra high field.
