Litigation disclosure redaction

Produce a court-ready copy with privileged fields and burned-in text redacted for legal disclosure.

Problem

A legal discovery request requires disclosure of medical imaging. However, only the clinically relevant regions may be disclosed — all other visual information (including PHI burned into the image) must be redacted. You need to selectively redact regions of the pixel data while preserving diagnostic content.

Steps

1. Open the DICOM file — click Open files… (⌘O).
2. Switch to Anonymization mode — click the Anon tab (⌘2).
3. Activate the redact tool — click the Redact tool in the top bar (or press R).
4. Draw redaction boxes over sensitive regions: patient name/ID overlays, institution logos, non-clinical annotations, or any identifying visual information.
5. Adjust boxes — drag corners to resize, drag center to reposition. Multiple boxes can be drawn.
6. Apply redaction — click Apply & Export. The exported DICOM has all redacted regions blacked out.
7. Verify — load the exported file. Redacted regions show solid black pixels. Diagnostic content outside boxes is unchanged.
8. Coordinate safety — out-of-bounds boxes are clamped to image boundaries. Zero-area boxes (single click, no drag) are rejected.

Expected Result

• Redacted regions appear as solid black pixels in the exported file.
• Diagnostic content outside redaction boxes is preserved.
• Multiple redaction boxes can be drawn and individually adjusted.
• Out-of-bounds coordinates are clamped to image boundaries (no crash).
• Zero-area boxes (single click) are rejected — no region registered.
