Reconstruction results for the cross-shaped object shown in (a). Reconstructions using single frequencies are shown for f = 0.5 MHz in (b), f = 0.9 MHz in (c) and for f = 1.9 MHz in (d). Panels (e–h) show reconstructions for designated frequency groups consisting of 3, 8, 16 and 26 frequencies, respectively. No noise was added to the synthetic measurements for these reconstructions.
