(a) First experimental validation of the DC recovery algorithm used in x-space reconstruction. DC recovery of the discarded first harmonic information produces a nearly identical PSF to a PSF where the analog received signal at the first harmonic was retained. (b) Experimentally reconstructed PSF for Triangle and Sine drive wave showing only minor differences. This is expected because a triangle and sine wave are similar, and the x-space theory in 1D shows that various trajectories with similar spatial sampling densities should yield the same reconstructed results, excepting variable impacts of magnetic relaxation. Importantly, this shows the triangle wave maintains conventional MPI performance while obviating velocity compensation which is a major reconstruction step.
