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.The investigation of log files shows that during the procedure the system entered backup review mode with limiting post processing functionality due to an image visualization system (ivs) host channel adapter (hca) printed wiring board issue.This means that due to the hca board issue the system switched to the "backup review mode", as it is intended for such cases, which is a mitigating factor for this issue.In this mode, radiation is available, and the images can also be displayed on the monitor in the examination room, but these images cannot be transferred to the ivs as desired and not further processed or sent on.If the problem was temporary only, all images would have been automatically transferred to the ivs after a restart and could have been processed further.In this case, however, this was not possible due to the ivs defect.The customer service engineer (ces) replaced the hca board and the fiber optical cable.After hardware replacement there were no further issues reported and the system works as intended.The occurrence rate of the identified cause has been checked and no error accumulation has been identified.The occurrence rate is below the defined threshold, therefore, no corrective action is necessary.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.
