This is the documentation for dynamic X-ray tomography measurements of a gel
phantom diffused with potassium iodide contrast agent. The measured data and
additional materials are available at http://www.fips.fi/dataset.php and Zenodo
(https://doi.org/10.5281/zenodo.3696817) for open use by the scientific
community, as long as the data and this documentation at arXiv are
appropriately referenced.
The files contain: (1) 17 consecutive measurements of the gel phantom
organized into sinograms at two different resolutions (binning levels) and some
additional metadata which can be used to create matrix-free forward operators
and filtered back-projection reconstructions; (2) the first measurement using a
greater number of projections, and an additional measurement of an 18th time
step using very dense angular sampling, for example to be used for reference
reconstructions; (3) short example codes to showcase how the data could be used
to test and validate reconstruction algorithms.Comment: Actual data can be found at https://doi.org/10.5281/zenodo.369681
