Wrong DOB / sex correction

Fix an incorrect birth date or patient sex and propagate it to all instances.

Problem

The Patient Birth Date or Patient Sex in a DICOM study is incorrect — the date was entered as 20051130 when it should be 19650315, or the sex was recorded as O instead of F. Wrong demographic data can cause the study to be excluded from cohort queries, misattributed to the wrong patient, or flagged by PACS validation. You need to fix these fields inline.

Steps

1. Open the file (⌘O) and switch to Edit mode (⌘3).

2. Filter for the tag — type “Patient Birth Date” or “Patient Sex” in the tag filter.

3. Double-click the row to open the Edit Tag modal.

4. Patient Birth Date (DA VR): enter the corrected date in YYYYMMDD format (e.g. 19650315). Any other format (slashes, dashes, text) is rejected with a red validation error.

5. Patient Sex (CS VR): enter M, F, or O. The value is stored as-is (CS VR accepts any short code string).

6. Click Save change and verify the gold highlighting.

Expected Result

• Patient Birth Date is updated and validated as exactly 8 digits (YYYYMMDD). Invalid formats like 1965/03/15 are rejected.
• Patient Sex is updated. The CS VR has no strict enumeration enforcement — any short string is accepted.
• Both changes increment the dirty counter and can be undone/redone with ⌘Z / ⌘Shift+Z.
