Zero-echo-time (ZTE) techniques enable imaging of tissues with very short T2s, e.g. bone or myelin. Their performance directly scales with gradient strength G, which depends on the target T2 and spatial resolution. With present-day gradients the spatial resolution for T2s on the order of 100 μs is limited to several millimetres. To improve the resolution, considerably higher gradient strengths are required. As a further challenge of ZTE sequences, the strong gradients are applied with full duty cycle. The goal of this work was to develop a gradient coil that meets these challenges, offering very high amplitude at full duty cycle.
