A head gradient prototype has been built. Its design enables high-performance imaging without compromise on patient ergonomics. Preliminary testing results on gradient efficiency, resistance, inductance, and eddy currents are presented. Data were compared to predictions and shows very good agreement. Next steps will include evaluation of peripheral nerve stimulation, and image quality. This work demonstrates substantial progress towards the development of a dedicated compact 3T head scanner.
