dc.descriptionThis 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. Each of these 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. Also MATLAB code for reconstructions using filtered back-projection, Landweber iteration, and Tikhonov regularization are provided. Documentation of the dataset is available at arxiv.org/abs/1609.07299. See also www.fips.fi/dataset.php.
