Travelling Wave MRI is an emerging method for large FOV imaging at ultrahigh fields. In this work, we investigate parallel imaging performance in traveling wave MRI using simple microstrip transceiver arrays. The two-element arrays were placed orthogonally at the end of the bore of a 7 Tesla whole body MR scanner for excitation and reception. MR experiment was performed demonstrating sufficient spatial diversity of B1 fields of each transceiver channel and good quality of parallel accelerated images.
