New StudyInstanceUID generation

Mint a fresh StudyInstanceUID to register an edited copy as a distinct study.

Problem

You’ve made significant edits to a study — corrected demographics, added missing tags, applied pixel transformations — and now the modified study needs a new Study Instance UID. Keeping the original UID would create a collision with the original study in the PACS. The DICOM standard requires derived or significantly modified studies to receive a new UID.

Note: In dcmage, UID regeneration happens automatically when you apply pixel transformations (Flip, Crop, Resample, etc.) or split/merge studies. For manual UID regeneration without a transform, you can trigger a lightweight pixel op.

Steps

Via Pixel Transform (Auto UID Regeneration)

1. Open the file (⌘O) and switch to Edit mode (⌘3). Record the original SOP Instance UID (0008,0018).

2. Open Pixel Operations — press ⌘K, type “Pixel operations”, and select it from the command palette.

3. Select Flip (or any transform) and click Apply transform. The derived copy automatically receives a new SOP Instance UID starting with 2.25..

4. Verify — filter for SOP Instance UID (0008,0018). The new UID is different from the original, non-empty, and starts with 2.25..

Via Study Split (Study Level UID)

5. For Study Instance UID regeneration, use Study Split in the Files panel (right rail):
   • Select the series, click the scissors icon (Split into separate study)
   • The new study receives a fresh Study Instance UID

Expected Result

• Derived copies receive a new SOP Instance UID with the 2.25. root.
• The new UID is mathematically distinct from the original (guaranteed by UUID-v5 derivation).
• Study Instance UID is similarly regenerated on study split.
• Frame of Reference UID is regenerated with dcmage.for prefix on study split.
