By projecting the CTs to a 2D plane, we gather fine-grained annotated imaages resembling radiographs. It contains 7,377 frontal and lateral view images each with 157 anatomy classes and over 2 million annotated instances.","description_withheld":null,"homepage":"https://github.com/ConstantinSeibold/ChestXRayAnatomySegmentation/","introduced_date":"2023-06-06","introduced_date_note":null,"introduced_by":{"paper":"/paper/accurate-fine-grained-segmentation-of-human","title":"Accurate Fine-Grained Segmentation of Human Anatomy in Radiographs via Volumetric Pseudo-Labeling","first_author":"Constantin Seibold","url":null},"license":{"name":"Attribution-NonCommercial-ShareAlike 4.0 International","url":"https://github.com/ConstantinSeibold/ChestXRayAnatomySegmentation/blob/main/LICENSE.txt"},"modalities":[{"name":"Biomedical","url":"/datasets/modality/biomedical"},{"name":"Medical","url":"/datasets/modality/medical"}],"tasks":[{"name":"Semantic Segmentation","url":"/task/semantic-segmentation","datasets_with_task":"/datasets/task/semantic-segmentation"},{"name":"2D Semantic Segmentation","url":"/task/2d-semantic-segmentation","datasets_with_task":"/datasets/task/2d-semantic-segmentation"}],"languages":[],"variants":["PAX-Ray++"],"data_loaders":[{"repo":"https://github.com/ConstantinSeibold/2DAnatomyDatasets","url":"https://github.com/ConstantinSeibold/2DAnatomyDatasets","frameworks":["pytorch"]}],"num_papers_in_archive":2,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
