Siemens has completed an investigation of the reported event.The root cause was determined to be a software error.As neither the log file nor any defective parts were available for examination, the cause of the error could only be determined retrospectively based on expert opinion.For reasons that cannot be determined retrospectively, the computer's software was corrupt, which led to the error described in the complaint.Since the system had malfunctioned and had to be put back into operation as quickly as possible, the service technician installed a backup image of the software, which eliminated the problem.There were no log files left from which further details could be determined, as these had been overwritten.Because no hardware was involved and the error was eliminated solely by installing software, experts agree that the cause of the error is corrupt software.The affected system software was re-installed by the local technical department and the error has not been reported again.A possible general error that would require corrective measures 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.
