We compared a fractal patterned micro-strip surface coil with a simple circular micro-strip surface coil for hyperpolarized 129Xe lung imaging applications. Both patterns were simulated using a finite element solver and electric and magnetic fields were calculated in the surface coil and adjacent air volume. The fractal-patterned coil showed relatively higher magnetic field compared to the circular coil in both the micro-strip surface and the air volume. Although, further simulations are required, fractal-patterned designs of MRI coils could offer specific improvement in signal penetration and magnetic field homogeneity.
