Figure 7

Illustration of the process by which optimal surface current patterns are generated. The first three plots from the left show current patterns for three arbitrarily chosen modes (l = 3, m = 0; l = 5, m = 3; l = 10, m = −10). The rightmost plot show the optimal current patterns, evaluated at every arrow position as the sum of the contributions of all current modes, weighted by the combination coefficients resulting in maximum SNR at a voxel in the center of the object. Optimal current patterns can be similarly computed for other voxel positions.
