Query: Tomographic X-ray data of carved cheese   This is the documentation of the tomographic X-ray data of a carved cheese
slice. Data are available at www.fips.fi/dataset.php, and can be freely used
for scientific purposes with appropriate references to them, and to this
document in http://arxiv.org/. The data set consists of (1) the X-ray sinogram
of a single 2D slice of the cheese slice with three different resolutions and
(2) 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.
