We investigated the role of parallel-transmit (pTx) RF coil arrays at 3 Tesla to control the RF-heating and local signal increases near the electrodes using computational field simulations on realistically modelled intra-/post-surgical simultaneous MRI-EEG measurement.
Electrode configurations of ROCA-ROLI(2),ROLI(1)-ROLI(2) and LCIP-LTFU with a table summarised their targeted tissue, brain hemisphere and number of electrodes.
RF shimming for the 16ch loop coil on the whole brain shown in the transverse plane, the 1st column illustrates the mean B1+ maps and the 2nd column the MIP of the SAR0.1g maps a) without electrodes b) with ROLI(2)-ROCA, normalised to 1W total input power.
