Recent years have seen a renewal in interest in low field MRI systems due to its lower cost, increased portability and robustness to medical implants, with the obvious disadvantage of lower SNR compared to clinical high field systems. In this work we present T1 and T2 relaxation maps of the brain and lower leg to facilitate the optimization of sequence parameters. Generally the T1 times are shorter and T2 times are slightly longer than at clinical field strengths.
