A study on the use of metasurfaces for magnetic resonance imaging of human body models

A numerical study of a radio frequency transceiver coil incorporating a capacitive metasurface is investigated for 1.5T magnetic resonance imaging of the cervical spinal cord. Full field simulations are carried out using the head of a human body model where the magnetic flux density (B 1 - ) is compared to a standard transceiver coil. It is shown that an average improvement in B 1 - of 70% can be observed inside the cervical spinal cord
