Enhancement of the signal received by the surface coil is one of the interesting area to increase the SNR. Left Handed Metamaterial Lens have shown application in MRI to increase the signal strength at its converging point. We have reported the increase in receiver sensitivity by around 5 dB. In this report SNR and Sensitivity is further improved by incorporating metamaterial lens in between 2 receive chain of a 4-channel hexagonal shaped flex array coil is presented. With this method SNR is improved by 1.4 times.
