Siemens has completed an investigation of the reported event.The root cause was determined to be a user error.The investigation was performed considering complaint description, cs reports, system history, and system log files.The customer stated that during an interventional procedure, after releasing the footswitch, the x-ray did not stop.The customer continued the procedure on this system.Siemens service was called and determined that during the procedure 110 fluoroscopy acquisitions were taken.Of these 110 acquisitions, 3 sequences were exceeding 30 seconds, including one with a duration of about 4 minutes.The user is able to recognize an ongoing radiation via an "xray" lamp.When checking the optical signal on site, no fault was found, and a functional test of the foot switch also did not reveal a defect.As no defect was found and the footswitch was working fine after the 4 minutes, the most likely root cause is that the footswitch was unintentionally pressed by the user.The footswitch was exchanged by the local service organization even though no malfunction was detected.A possible general error which would require corrective action of the installed base could not be identified 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.
