a: Location and size of the object used in the simulations. The size of the object is 96 mm and the FOV is 256 mm. The vertical lines show the location of voxels when the discrete FT is used for spatial reconstruction. For SLIM and NL-CSI reconstruction voxels 6-12 were chosen as regions (total = 7). Only half regions of voxels 6 and 12 were selected (i.e., where the object is present). b and c: Reconstructed signals from voxels 6 and 9 with T2 = ∞. FT and SLIM reconstructions show substantially nonlinear behavior. In voxel 6 the signal peaks around 70 ms and then decays rapidly. NL-CSI reconstruction shows constant linear signal with time, as expected. d and e: Reconstructed signals from voxels 6 and 9 with T2 = 50 ms. The plots show that FT and SLIM reconstruction lead to severely distorted FID signal, whereas NL-CSI reconstruction shows true exponential decay of the signal.
