Metamaterials (MTMs) have been used as passive elements to improve the receive sensitivity in MRI by enhancing the field locally, but not connected directly as receive elements. We present the design and construction of a novel 2D transmission line based MTM employed as a 4-port element combined with an additional 4-element coil array. Simulation and measurement of receive sensitivity are compared to those of a conventional 8-element coil array covering the same region. The receive sensitivity in a human torso sized phantom is found to be equivalent, while the MTM slab additionally enhances the transmit performance.
