Abstract

Continuous fluoroscopic data is acquired using magnetic resonance imaging by applying magnetic gradients to excited nuclei whereby emitted magnetic resonance signals traverse interleaved spirals in k-space. The spirals can have tighter loops near the origin of k-space to emphasize lower frequencies.
