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.
