This is an open-access dataset of tomographic cone-beam X-ray data of a dynamic agarose-gel phantom perfused with a liquid contrast agent. The dataset consists of 17 consecutive X-ray measurements of a 3D volume of the gel phantom. This data is provided in three resolutions and stored in a special CT-data structure containing the metadata of the measurement setup.
In addition a denser projection sampling of the first time step, and a very dense sampling of an addition 18th time step is provided as a complementary data.
The data does not contain the corresponding forward operators as is, but allows for easy creation of computationally efficient matrix-free operators and FDK reconstructions on CUDA cabable GPUs.
The data is licenced under an open data licence (CC BY 4.0) and it is hosted on Zenodo.
