We present a model for k-space trajectory shifts due to
independent timing delays in gradient channels. We use
this model to successfully detect and correct for
gradient delays in 3D golden angle radial MRI data
without the need for additional data collection,
calibration, or hardware measurements. The method can
also be used for 2D radial or other non-Cartesian
trajectories with only slight modifications.
