Multiple coils shimming technology has been demonstrated as a promising approach to reduce the B0 inhomogeneity in MRI. However, strong coupling arises when local DC coils are placed close to the imaging area and RF coils. To solve this problem, we proposed a novel local DC shim coil that has little effect on the RF coils, which we called "RF transparent" DC coil. This concept was validated by EM simulation, bench test, and MR experiments. The RF transparent concept will bring much more freedoms to DC coil design (such as many turn and irregular shaped).
