Scaling MPI imaging hardware to image a human head presents challenges for the primary drive and receive coils. The larger imaging volume necessitates increased inductance, power delivery, and large physical sizes. Here, we present human-head scale drive and receive solenoid coils in a split gradiometer configuration designed for a mechanically-rotating field-free line MPI system. The design efficiency allows for 8mT drive fields (at ?26 kHz) from the water-cooled drive coil using an amplifier providing 21 A RMS and ?120 V RMS into the drive filter. The geometric decoupling between the drive and Rx coil of the gradiometer pair is -52 dB.
