Misspelled patient name correction

Correct a misspelled PatientName across every instance in the study.

Problem

A DICOM study has a misspelled Patient Name — “SMITH^JON” instead of “SMITH^JOHN”. This typo prevents the study from linking correctly to the patient’s other records in the PACS. You need to fix it directly in the DICOM headers without re-sending the study from the modality.

Steps

1. Open the DICOM file — click Open files… (⌘O).

2. Switch to Edit mode — click the Edit tab in the mode switcher (⌘3).

3. Find the Patient Name — type “Patient Name” in the tag filter box to bring the row into view (the tag tree is virtualized — filtering ensures the row is in the DOM).

4. Open the editor — double-click the Patient Name row. The Edit Tag modal opens showing the current value.

5. Enter the corrected name — type SMITH^JOHN and click Save change.

6. Verify — the row turns gold (modified highlight) and the dirty counter in the top bar shows “1 modified”.

7. Undo if needed — click Undo (⌘Z) in the metadata toolbar to revert. The gold highlight disappears and the dirty counter clears.

8. Redo — click Redo (⌘Shift+Z) to re-apply the edit. The counter returns to “1 modified”.

Result

The corrected Patient Name shows gold and the dirty counter reads 1; ⌘Z restores the original and clears the counter, ⌘⇧Z re-applies it. The PN VR is enforced, so a component over 64 characters is rejected before saving.
