Numerical simulation. Top: a) numerically simulated short axis image. b) Image a shifted horizontally half a pixel by phase-shifting the raw-data. c) Image a shifted vertically half a pixel using the same method. d) Image a with lower LV/myocardium signal ratio. Images e-h are images a-d interpolated in the image space. Images i-l are images a-d zero-filled pre-FFT. Both figure 3 a, and d also show, in the top right corner, the correspondent measured peak artifact signal loss.
