Comparison of modeling errors in sagittal liver images of a healthy volunteer. (a) (top) A library image (sum-of-squares across coils) and (bottom) image phase for a single coil. The phase is smooth in the liver center, but varies rapidly near the ribs. The highlighted region in (a) is shown across library images in (b) to illustrate the up-down motion of the liver. (c) shows residual temperature errors and standard deviations after estimation with the three methods in eight subsequently acquired images. The hybrid model is more accurate than the other two methods in both the inner liver and over the liver/rib interface region.
