Velocity measurements and whole polynomial fit in an axial slice of a static phantom.

<p>The top row shows the measured velocity in the phantom and the bottom row shows the whole brain polynomial fit. Measurements corresponding to these images can be found in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0149930#pone.0149930.t001" target="_blank">Table 1</a>.</p>
