Figure 8

Simulation of the performance of a 32-element head array with respect to the ultimate intrinsic SNR. Loop coils were arranged in software around a spherical object to obtain a configuration similar to the array in Figure 2 (left plot). Current modes in our basis set were then weighted with appropriate coefficients in order to reproduce the current patterns corresponding to this conductor geometry (center plot). The SNR of the array was calculated using the DGF method on a transverse FOV and the resulting values were reported as a percentage of the optimum by means of a performance map (right plot). The maximum and the mean performance are indicated in brackets above the map.
