Series concatenation

Concatenate separate series into a single contiguous series.

Problem

Two series from the same study should be concatenated into one — e.g. a CT scan that was interrupted and resumed produced two Series Instance UIDs, but clinically it’s one continuous acquisition. Concatenating them under a single series simplifies viewing (one scrollable stack instead of two).

Steps

1. Open the files (⌘O) and switch to the Files tab.

2. Ensure both series are under the same study — use Merge dropdown or drag-and-drop if they’re under different study headers.

3. Use the Merge series dropdown on one series row to absorb the other series into it.

4. Verify — the tree shows one series row. Switch to View mode to confirm all slices are in a single scrollable stack.

Expected Result

• Two series consolidated into one series row in the Files tree.
• All slices from both original series scroll together in the viewport.
• The surviving series retains its Series Instance UID; the absorbed series’ identifier is discarded.
• The merge is undoable — ⌘Z restores the two separate series.
