    Abstract: Various methods and systems are provided for correcting k-space trajectories. In one embodiment, a system comprises a coil configured to generate a magnetic field, a plurality of magnetic field probes positioned at the coil and configured to measure the magnetic field, and a controller communicatively coupled to the plurality of magnetic field probes and including instructions stored in non-transitory memory that when executed cause the controller to: receive measurements of the magnetic field from the plurality of magnetic field probes; calculate corrections to positions of acquired magnetic resonance signals in spatial-frequency space based on the received measurements; apply the corrections to the positions to generate corrected magnetic resonance signals; and reconstruct an image from the corrected magnetic resonance signals. In this way, image artifacts caused by eddy currents can be reduced.

    Abstract: A magnetic resonance imaging (MRI) gradient coil assembly includes a substrate and first hollow conductor coil. The substrate has a surface. The first hollow conductor coil includes a first coiled portion and a first end run portion joined by a first eye lead portion. The first coiled portion defines a series of increasing radius loops disposed on the surface of the substrate, with an outer loop of the first coiled portion defining a coiled portion boundary. The first eye lead portion is disposed in a central portion of the first coiled portion. The first end run portion extends continuously from the first coiled portion via the first eye lead portion beyond the coiled portion boundary.
