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.
