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)
-
Open the file (⌘O) and switch to Edit mode (⌘3). Record the original SOP Instance UID (0008,0018).
-
Open Pixel Operations — press ⌘K, type “Pixel operations”, and select it from the command palette.
-
Select Flip (or any transform) and click Apply transform. The derived copy automatically receives a new SOP Instance UID starting with
2.25.. -
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)
- 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
Result
Derived copies receive a new 2.25. SOP Instance UID that is mathematically distinct from the original (UUID-v5), and a study split likewise regenerates the Study Instance UID and a dcmage.for Frame of Reference UID.
