The Imaging Data Common (IDC) dataset is a comprehensive repository of medical imaging data hosted by the National Cancer Institute, providing a natural language interface for exploration and analysis. It encompasses a wide array of cancer-related collections such as APOLLO, CCDI, CDDP-EAGLE, CGCI, and the Cancer Moonshot Biobank, alongside specific analysis results like CPTAC-CCRCC-Tumor-Annotations and PROSTATex-Seg-HiRes. The dataset features diverse modalities including CT, radio fluoroscopy, and external-camera photography, covering various body parts and cancer types ranging from colon mucinous adenocarcinoma to pathologically benign hemangioma. Accessible under multiple Creative Commons and National Library of Medicine licenses, IDC serves as a vital resource for advancing oncological research, imaging segmentation, and computational analysis within the broader scientific community.
