Keywords: New Devices, Spinal Cord, Metamaterial, MetasurfaceSpine imaging is usually conducted at 3T given the need of high spatial resolution. Unfortunately, the lumbar and thoracic spine regions of interest will lie in areas of weak transmit efficiency. Recent studies showed that high permittivity ceramic blocks can improve image quality. Here we present a new approach based on ultra-thin, lightweight, flexible metasurface pads yielding improved efficiency and homogeneity of the B1+ field along the spine in clinical 3T MRI settings. Our design offers seamless integration to regular equipment leading to more efficient and safer spine imaging protocols.
