Engineering Notes
The bridge between DICOM and RIS/HIS systems. Must be populated from the Modality Worklist. Missing or wrong Accession Number breaks report-to-image linking in the radiologist's workflow.
Troubleshooting
If reports cannot be linked to images in PACS, verify Accession Number is flowing correctly from RIS to modality via Modality Worklist. Check case sensitivity and leading-zero handling between systems.
