Carved cheese (FIPS)
A single 2D slice of a carved cheese from the Finnish Inverse Problems Society, published at three resolutions together with the measurement matrices that encode the X-ray transform as an explicit linear operator. Getting the forward operator handed to you alongside the sinogram removes an entire class of geometry-matching bugs, which is why it stays a standard first test whenever a reconstruction method is ported onto real measured data. Documentation lives at arXiv:1705.05732.
