Wrong AET tag rewrite

Rewrite tags populated with the wrong Application Entity Title.

Problem

A DICOM file was incorrectly routed to the wrong Application Entity Title (AET). The Called AE Title (0008,0051) or Calling AE Title (0008,0050) tags contain the wrong value, preventing the file from reaching its intended PACS destination. You need to correct these AE tags before resending.

Steps

1. Open the DICOM file — click Open files… (⌘O).
2. Switch to Edit mode — click the Edit tab (⌘3).
3. Find the AE Title tags — in the tag filter box, type “(0008,0050)” for Calling AE Title or “(0008,0051)” for Called AE Title.
4. Edit the tag — double-click the row. In the Edit Tag modal, replace the incorrect value with the correct AE Title (e.g. DCM4CHEE). The VR (AE) enforces a maximum length of 16 characters.
5. Save — click Save change. The row turns gold (modified highlight).
6. Verify — the AE Title now shows the corrected value. The file can be resent (use case 7.1.2) to the correct PACS destination.
7. Validation — entering a value longer than 16 characters is rejected with a red VR validation error: “Must be less than or equal to 16 characters”.

Result

The corrected AE Title shows gold and the dirty counter rises for each modified AE tag; the AE VR caps values at 16 characters, rejecting anything longer. The file is then ready to resend to the right PACS via C-STORE.
