RabbitCT: a C-arm cone-beam CT benchmark dataset

Archival re-release of the RabbitCT benchmark dataset: an open platform for benchmarking 3-D cone-beam CT backprojection algorithms on a single high-resolution C-arm CT scan of a post-mortem rabbit. The original challenge website (www5.cs.fau.de) is no longer online; this copy is published with the authors' agreement to keep the benchmark available. Contents: rabbitct_512.rctd and rabbitct_1024.rctd (496 projections plus calibrated 3×4 projection matrices, for 512³ and 1024³ reconstruction targets), reference_256.vol (256³ float32 reference reconstruction), and the developer kit (rabbitct_develop.zip: data structure header, CMake project, and the LolaBunny example backprojection module). See README_data.md for the file format and geometry. Ethics: post-mortem acquisition; no live-animal procedure. Please cite: Rohkohl C, Keck B, Hofmann HG, Hornegger J.
