Hazard: System operator manual states that the system should be rebooted once, every 7 days. In some cases, users are not following these instructions and the system is running for more than 7 days. Under rare circumstances, this may result in a partial freeze of the user interface which would no longer update the vital signs

Hazard: Software error, the software can produce an incorrect interpretation of the table rotation if the table has been rotated by more than 4degrees in either direction. This can cause the 3D image reconstruction to be shown rotated by up to 5 degrees relative to the patient and to be used inappropriately by the system and result in incorrect treatment of the patient

Hazard: Software versions may result in sporadic problems causing scanning workflow interruptions and unexpected user notifications. Sporadic software errors may also occur during interventional workflows, resulting in delay in diagnosis or scan aborts with the necessity for patient rescan may occur

Hazard: Due to intermittent failures of the power supply in the ultrasound system which renders it inoperable.

Hazard: Potential for data loss when using the contouring or patient marking workflow when editing a structure set after saving and reopening a study, resulting in an incomplete structure set sent to the treatment planning system (TPS).

Hazard: Due to a software error, the IAS (Image Acquisition System) may sporadically fail during startup/ restart, and result in delay of clinical treatment

Hazard: Software error VE10B -In case of a fault within the drivetrain of an axis and while performing a stepped peripheral imaging (PERISTEPPING/PERIVISION), the C-arm may leave its intended travel path by up to 22 cm (9") result in canceling clinical treatment or to continue treatment on an alternative system

Hazard: 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.

Hazard: Siemens has become aware of a potential issue with software version VE20C. Planned procedures may have to be terminated and performed on an alternative x-ray system.

Hazard: Due to inappropriate cleaning, some Artis systems show unexpected corrosion of visible belts which are needed to move system parts (e.g. C-Arm), Increased corrosion may lead to a malfunction of the belts which may result in limited functionality of the Artis system up to system failure. Unintended movement of the C-Arm may cause a hazardous situation to the patient, operator, or staff members and may result in a situation where it is necessary to cancel clinical treatment or to continue treatment on an alternative system
