Restructuring

One study → multiple studies split

Split a single study into multiple studies by regrouping its series.

Problem

A single study contains series that should belong to separate studies — e.g. a chest CT and an abdominal CT were grouped under one Study Instance UID due to a modality worklist error. These need to be split into independent studies so each can be reported separately, routed to different worklists, or anonymized with different parameters.

Steps

Open the files (⌘O) — load a folder or multiple DICOM files containing the series to split.
Switch to the Files tab in the right rail to see the study tree.
Split a series into a separate study — click the scissors button (Split into separate study) on the series you want to move. The tree updates: two study headers now appear, each with its own series.
Merge studies back (if needed) — use the Merge dropdown in a study header to absorb another study’s series. After merging, only one study header remains with all series grouped under it.
Verify UID regeneration — the newly split study receives a fresh Study Instance UID and Frame of Reference UID (with dcmage.for prefix).

Expected Result

After split: two study headers in the Files tree, each with distinct Study Instance UIDs.
After merge: one study header with all series grouped together.
Frame of Reference UID on the split study is regenerated and differs from the original.
The dirty counter tracks structural changes.
Drag-and-drop between study headers is also supported — drag a series row onto another study header to reassign it.
