This is an open-access dataset of tomographic X-ray data of a slice of a lotus root. The dataset consists of
- the X-ray sinogram of a single 2D slice of the lotus root with two different resolutions, and
- the corresponding measurement matrices modeling the linear operation of the X-ray transform.
Also MATLAB code for reconstructions using filtered back-projection, Landweber iteration, and Tikhonov regularization are provided.
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 hera as a video:
