Scout/localizer purge

Remove scout/localizer series that aren't needed for review or archival.

Problem

Your DICOM folder includes scout/localizer images — low-dose planning scans used for slice positioning — alongside the diagnostic CT series. Scouts are not diagnostic quality but they inflate the series count, confuse automated processing pipelines, and take up storage space. You want to automatically detect and purge all scout series from the study.

Steps

1. Open the files (⌘O) — load a folder containing both a diagnostic CT series and a scout/localizer series (e.g. test.dcm and scout-test.dcm).

2. Switch to the Files tab in the right rail. Verify that two study headers are visible (scouts typically have a different Study Instance UID from the diagnostic series).

3. Check the Purge button — a Purge scouts button is visible in the Files panel toolbar. The button shows the count of detected scout series, e.g. Purge scouts (1).

4. Click Purge scouts — the scout study is removed from the tree. Only the diagnostic CT study remains.

5. Verify — the Purge button counter drops to (0), and the study header count decreases.

Expected Result

• Scout series are automatically detected and flagged by the Purge scouts counter.
• After purging, only diagnostic-quality series remain.
• The purge is undoable — ⌘Z restores the scout series.
• The counter updates to reflect the current scout count after cleanup.
