STEMPO—Dynamic X-Ray Tomography Phantom

This is the documentation for the Spatio-TEmporal Motor-POwered (STEMPO) phantom for dynamic X-ray tomography. Different measurements designed for testing dynamic tomography reconstruction algorithms are provided. The measured data and additional materials are available at http://www.fips.fi/dataset.php and Zenodo for open use by the scientific community, as long as the data and this documentation are appropriately referenced. The files contain: (1) measurement data (sinograms) from one static scan and two dynamic scans (same movement but different choice of projection directions). All data is provided both for 2D and 3D geometry in varying resolution levels; (2) approximation of the ground truth obtained using the known motion model; and (3) short example codes to showcase how the data could be used to test and validate dynamic tomography algorithms.
