Value Title Meaning Description Broad Mappings Stage Number
DATA_EXTRACTION_AND_METADATA_CHARACTERIZATION Data extraction and metadata characterization Extraction of imaging data from clinical repositories such as PACS, preceded by a landscape assessment of source locations, database systems, modalities and acquisition devices NCIT:C44285 1
FILE_INTEGRITY_VERIFICATION File integrity verification Computation and periodic re-verification of cryptographic checksums such as SHA-256 to detect silent corruption from network errors, media decay or system failure NCIT:C142477 2
DATA_COMPLETENESS_AND_CONFORMANCE_CHECKS Data completeness and conformance checks Detection of structurally invalid DICOM files (truncated, wrong VR encoding, missing required tags) and checks of internal coherence such as identifier uniqueness and demographic consistency across sites 3
METADATA_TAG_VALIDATION Metadata tag validation Validation of DICOM attributes against the standard's VR, VM and type rules and against biological plausibility, and inventory of private tags NCIT:C142500 4
IMAGE_QUALITY_AND_PIXEL_DATA_VALIDATION Image quality and pixel data validation Verification that pixel data is readable and plausible, that decompression preserves bit depth, and computation of image quality metrics 5
DEIDENTIFICATION Pixel-level and metadata de-identification NCIT:C45970 Removal of protected health information from headers and of facial features from pixel data before sharing and reuse 6
