Image of a carved cheese and its reconstructions from 45 projections (middle) and 15 projections.

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.

The data is licensed under an open data license (CC BY 4.0) and it is hosted on Zenodo.

An informal video report of the data measurement session is available here as a video:
