Is this trial a fit for you?

Likely a good fit

Adults (18+) undergoing intraoperative radiography for suspected retained foreign objects.

Probably not a fit

Patients whose radiographs are not suitable for AI processing or have no retained object risk may not benefit.

What this trial studies

This is a prospective, non-interventional study that runs silently to evaluate an AI system’s ability to detect retained foreign objects on intraoperative radiographs. Radiographs from routine care are automatically processed by the AI in real time for about a year. The AI outputs—such as detection probabilities and localization notes—are not shown to clinicians and do not influence treatment. Performance will be measured against reference standards using radiology reports, operative notes, and follow-up imaging when available.

Why it matters

Potential benefit: If successful, the AI could provide a reliable tool to help verify that no objects are left behind in future procedures.

How similar studies have gone: Other AI approaches for medical image Review have shown promising results, but this specific silent, non-interventional setup is relatively novel.

Inclusion Criteria:

* Age 18 years or older.
* Undergoing intraoperative radiography during routine clinical care for evaluation of a possible retained foreign object.
