We present numerical optimization of variable winding pitch coil designs for miniature coils with respect to target field homogeneity. The optimization is based on a continuous coil winding layout that was used to simulate field homogeneity in the target volume via the Biot-Savart law. The example coil designs expand the range of applications for frequency adjustable field probes, as they increase the B0 modification field’s homogeneity by factor of 7. Due to the specific requirements of miniature B0 modification coils, the dimensions of the coil are restricted in length, width and wire diameter.
