This study presents a numerical approach to simulate artifacts of metallic implants in the MR environment, which can be applied to improve the MR image artifacts testing procedure for medical implants according to ASTM F2119. The numerical approach is validated by comparing simulations and measurements of two metallic test objects made of titanium and stainless steel at three different field strengths (1.5 T, 3 T, and 7 T).
