<p>This is an open-access dataset of tomographic X-ray data of a slice of a lotus root. The dataset consists of</p>
<ul>
<li>the X-ray sinogram of a single 2D slice of the lotus root with two different resolutions, and</li>
<li>the corresponding measurement matrices modeling the linear operation of the X-ray transform.</li>
</ul>
<p>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.</p>
<p>Also MATLAB code for reconstructions using filtered back-projection, Landweber iteration, and Tikhonov regularization are provided.</p>
<p>Documentation of the dataset is available at <a href="https://arxiv.org/abs/1609.07299">arxiv.org/abs/1609.07299</a>. See also <a href="https://www.fips.fi/dataset.php">www.fips.fi/dataset.php</a>.</p>
