This is an open access dataset of tomographic X-ray data of emoji phantom. The dataset consists of
- the X-ray sinogram of a single 2D slice of 33 emoji faces (contains 15 different emoji faces) made by small squared ceramic stones, and
- the corresponding static and dynamic measurement matrices modeling the linear operation of the X-ray transform.
Each of these sinograms was obtained from a measured 60-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 licenced under an open data licence (CC BY 4.0) and it is hosted on Zenodo.
