Keywords: Gradients, Gradients
Motivation: High performance gradients enable fast and high-resolution imaging but are costly and cumbersome to install in an existing MRI-system
Goal(s): Present a wireless (resonant) gradient coil setup that yields additional gradient performance without needing a dedicated amplifier
Approach: The increased gradient performance was measured using field camera measurements and acceleration performance was assessed retrospectively using phantom experiments
Results: The wireless gradient yielded a factor 23 improvement in slew rate (from 125 T/m/s to 2900 T/m/s) and 28-fold retrospective acceleration resulted in aliasing free images.
Impact: A wireless insert gradient coil enables 28-fold accelerated scanning without a supplementary gradient amplifier. This provides a cost-effective pathway for improving gradient performance with minimal system modifications.
