We have designed a phantom that, unlike the Shepp-Logan phantom, is difficult to reconstruct with compressed sensing MRI techniques. This phantom is not sparse under a gradient transformation and contains many features susceptible to corruption under a partial Fourier measurement operator. And unlike real images, the phantom has no noise, so it may be used for exact measurements of noise-free reconstruction accuracy.
