A slim TMS-compatible MRI 10-channel RF coil array was developed. The coil array was 2 mm thick to maximize TMS efficacy and positioning freedom. Empirical data show that the average SNR of TMS-compatible coil array is 44% better than the commercial 32-channel array within the 5 cm depth. This TMS-compatible RF coil array is expected to offer both anatomical images and functional MRI signal induced by TMS with high sensitivity.
