Additional Manufacturer Narrative
Siemens has completed an investigation of the reported event.The root cause was determined to be a hardware error.The investigation was performed considering complaint description, cs reports, system history, and system log files.During an interventional procedure, automatic stand movements were not possible.The user was informed about this error by the error message "manual gantry rotation: active".Basic functions such as x-ray and general manual stand movement were still available.With this residual functionality, the procedure can be stopped/aborted in a controlled manner if necessary.On-site troubleshooting revealed that plane a's c-arm was not engaging around the base because a base rotation light mark sensor was mechanically out of alignment.After replacing the light sensor, the systems works as intended.The occurrence rate of the error pattern was checked.A possible error accumulation or even a systematic error, which leads to a corrective action of the installed base, could not be determined by the investigation.After detailed investigation, the incident is not classified as a reportable event as neither serious injury, death nor an unexpected, prolonged hospitalization of the patient or any other person occurred or could be expected.
