A simulation framework is presented to optimize radial acquisition schemes with variable echo times which are designed to minimize the directional anisotropy of the artifact of an MR-safe guidewire. The simulation results are compared to measurements. We could theoretically and experimentally verify that the homogeneity of the artifact can be improved via the variable-TE method.
