StudyDate/Time correction

Fix an incorrect study date or time left by a scanner clock error.

Problem

The Study Date or Study Time on a DICOM file is wrong — the modality’s internal clock was off by a day, or the time zone wasn’t configured correctly. Incorrect temporal metadata breaks study sorting in the PACS, affects hanging protocol matching, and can cause compliance issues with report turnaround time tracking.

Steps

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

2. Study Date (0008,0020) — filter, double-click, enter the correct date in YYYYMMDD format (e.g. 20260607). The DA VR validator enforces exactly 8 digits. Invalid formats are rejected:

   • 2026/06/07 (slashes) → “Must be exactly 8 digits: YYYYMMDD”
   • INVALID_DATE (text) → rejected, save button disabled

3. Study Time (0008,0030) — filter, double-click, enter the correct time in HHMMSS or HHMMSS.FFFFFF format (e.g. 231800). The TM VR validator rejects non-numeric formats:

   • 12 o-clock (text) → rejected, save button disabled

4. Click Save change for each field. Both appear gold-highlighted.

Result

Study Date and Study Time are corrected and validated against the DA and TM VRs; invalid input disables Save and shows a red message explaining the expected format. The dirty counter increments, and the corrected values sort correctly in PACS queries.
