  This is the documentation for Spatio-TEmporal Motor-POwered (STEMPO) phantom
for dynamic X-ray tomography. Provided are different measurements designed for
testing dynamic tomography reconstruction algorithms. The measured data and
additional materials are available at www.fips.fi/dataset.php and
doi.org/10.5281/zenodo.7081688 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.
