MR imaging has a significant role in medical diagnostics. Imaging quality depends on SNR levels. Higher B0 field and consequently higher RF-field intensity increase SNR but it also elevates the total body SAR. This can be alleviated by local magnetic field enhancement. Metamaterial based structures have shown promising applications in this regard. Here we report a new metamaterial inspired resonant structure for local field enhancement in 3T MRI machine. We show field enhancement capabilities of our design in planar and cylindrical forms, each of which can be used based on the anatomical site under investigation.
