Engineering Notes
Used by PACS to distinguish original acquisitions from derived/processed images, CAD outputs, and screen captures. Value 1 ORIGINAL vs DERIVED drives many PACS archival decisions.
Troubleshooting
PACS auto-delete or thin-client filtering rules often key on Image Type. Unexpected deletion of series may be caused by the modality incorrectly labelling reconstructions as DERIVED.
