Recently, studies on parallel accelerated imaging with traveling-wave have been reported. In this work, the method of implementing parallel traveling-wave using single-feed quadrature patch antenna transceiver array was investigated and validated using MR experiments on a 7T whole body MR scanner. A two-element patch antenna array was built, and a human head phantom was positioned 85 cm away from the patch antenna array in experiment. Excellent parallel imaging performance in both axial and sagittal planes at acceleration factor of 2 was demonstrated with both SENSE and GRAPPA accelerated imaging.
