DCM Sample Files
DICOM (.dcm) files are the standard container for medical imaging data, combining pixel payloads with patient/study/series metadata and transfer syntax details. Use sample .dcm files to validate medical image viewers, metadata extraction, anonymization pipelines, and modality compatibility across CT, MR, and secondary-capture workflows.

# Compare output with SHA256 values listed above.Where is the machine-readable manifest?
Use the manifest when you need stable names, SHA256 values, and URLs for automation.
Use in code — curl, Python, Node, wget
Copy any snippet directly into scripts, test suites, or CI pipelines. All URLs are stable and publicly accessible with no auth required.
