CT Reconstruction Datasets and Benchmarks
21 datasets and 11 benchmarks from the directory have a page of their own, with the data they contain, their licence, the topics they belong to and the papers in the directory that use them.
Another 28 entries, mostly segmentation and detection collections with no reconstruction topic or paper in the directory yet, are listed in the full dataset table and benchmark table.
