Fig. 4.

This figure shows the $R^2$-maps that demonstrate the proportion of true variance in the simulated off-resonance fields explained by a first order model. The left column shows $b=0$ images for anatomical guidance. The middle and rightmost columns show the $R^2$-maps for the “normal” and “large” movement simulations respectively. The grey-scale goes from 0 (black) to 1 (white).
