The tube is mounted together with a cassette holder to the ceiling suspension telescope arm (trauma support block), which allows easy positioning in horizontal and vertical direction.Tube and cassette holder have a fixed relative position via the so-called trauma arm that can be rotated.Investigation showed that 2 of the 3 trauma support block fixing screws cracked out of its thread and the third screw sheared off.Nobody was in the examination room at the moment the trauma arm fell down onto the table.The field service engineer exchanged the affected shaft and 3 new fixing screws.Philips will publish a field safety corrective action regarding this problem ((b)(4)) in august 2015.(b)(4).
