You can download DICOM imaging data without authentication by querying the IDC index with idc-index, which retrieves publicly available radiology and pathology datasets directly to structured local directories.

Filtering IDC imaging datasets by modality and body part is supported. You can query the IDC index metadata to narrow results by collection, modality, body part, and licensing before downloading.

The best way to query public radiology data for batch workflows is using idc-index to filter IDC collections and save query results as manifests, ensuring reproducible data retrieval across pipeline runs.

idc-index supports visualizing DICOM data previews in a browser. You can browse queried IDC imaging data in a viewer to verify content before downloading the files.

To check licensing for IDC datasets before downloading, query the IDC index metadata to filter by license and verify the data usage terms associated with each collection.

idc-index 0.11.10 targets IDC data version v23 for compatibility and reproducibility, ensuring that queries and downloaded DICOM data remain consistent across environments.
