Figure 2

(a) ENLIVE reconstructions of the same data as in Fig. 1 using 1, 2, 3 and 4 sets of maps. Difference images to fully-sampled reference data are shown in the bottom row. Using a single map, the central artifact is clearly visible in the reconstruction as well as in the difference image. Using 2 and more maps, the artifact is resolved and the difference images show close to no variation. (b) Individual map images of the reconstruction using 4 maps. Since 2 sets of maps are sufficient to fully describe the data, the first two maps are similar to the maps depicted in Fig. 1 while maps 3 and 4 are close to zero. The corresponding coil profiles are depicted in Fig. 3.
