Evolution of TrACR-SENSE images and trajectory error estimates versus TrACR outer loop iteration, for a center-out radial reconstruction. (a) Images and magnitude differences between the TrACR image and an image reconstructed using a measured k-space trajectory, versus number of TrACR iterations. (b) Corresponding k-space error estimates, plotted with the final TrACR trajectory error estimate and the measured trajectory error.
