Product Description
Multitom RAX with software version VF10
Reason for Recall
Siemens identified two issues, In some cases, it is possible to perform an image acquisition although more than 20% of the beam does not hit the detector. This may only occur when an organ program for the wall mode without top alignment is selected and the system is moved to the centred position. If afterwards the operator activates the top alignment, increases the collimation, and lifts the tube, the system allows examination even with the tube being misaligned to the detector position. Hence, it is possible to overshoot the detector by more than 20%. From a clinical point of view, it is highly unlikely for the operator to trigger the examination as the misalignment is visible due to the light field being out of range. AND In very rare cases it may occur that the calculated dose value exceeds the limit of 2 Gy. This may potentially occur only when an organ program for free exposure is selected, and the system uses incorrect (too small) source-to-image distance (SID) for calculating applied dose. Hence, the calculated dose is much higher than the actual applied dose causing the buzzer, which normally notifies the operator about the exceeded limit of 2 Gy, to get activated erroneously.

Frequently Asked Questions
Contact your healthcare provider and the device manufacturer immediately. Check whether your specific model number and lot number are included in the recall scope. For external devices, stop using the affected product and arrange a replacement. For implanted devices, do not panic — removal is typically not required unless the risk assessment clearly indicates it. Your physician will guide you based on your individual clinical situation and the FDA's recommended actions. Report any adverse effects you may have experienced to FDA MedWatch at 1-800-FDA-1088.
Class I recalls indicate a reasonable probability of serious adverse health consequences or death from the defect. Class II recalls involve products that may cause temporary or medically reversible adverse health consequences, or where serious consequences are remote. Class III recalls cover products not likely to cause any adverse health consequences, typically involving technical regulatory violations. The classification guides urgency — Class I recalls require immediate action, while Class III may simply involve returning a product or acknowledging a labeling change. Always read the specific recall notice for recommended patient actions.
Report problems with medical devices to the FDA through MedWatch at 1-800-FDA-1088 or online at FDA.gov/safety/medwatch. Healthcare facilities are required by law to report device-related serious injuries and deaths. Patients and consumers can also report voluntarily. Include the device name, manufacturer, model number, and a description of the problem and any patient outcome. Reports from patients and clinicians help the FDA identify emerging safety signals and may trigger investigations that lead to recalls of dangerous devices.
What Should You Do?
Stop using this device if you are affected by this recall. Contact your healthcare provider and the manufacturer immediately for guidance. Report adverse events to FDA MedWatch.
