 Abstract: Here we present simulated and experimental results combining an array of counter rotating current (CRC) surface coils and a TEM volume coil in transmission. The combination provides better homogeneity than the TEM alone for excitation, and simulated results are in good agreement with experiment for combining a 4-element array with the TEM. Further simulation shows a much improved result for increasing the number of CRC coils in the array to 8.
