This is an open-access dataset of tomographic X-ray data of a carved cheese. The dataset consists of

  • the X-ray sinogram of a single 2D slice of the cheese slice with three different resolutions, and
  • the corresponding measurement matrices modeling the linear operation of the X-ray transform.

Each of the sinograms was obtained from a measured 360-projection fan-beam sinogram by down-sampling and taking logarithms. The original (measured) sinogram is also provided in its original form and resolution.

Documentation of the dataset is available at arxiv.org/abs/1705.05732. See also www.fips.fi/dataset.php.
