Reason for recall

Siemens identified two issues, In some cases, it is possible to perform an image acquisition although more than 20% of the beam does not hit the detector. This may only occur when an organ program for the wall mode without top alignment is selected and the system is moved to the centred position. If afterwards the operator activates the top alignment, increases the collimation, and lifts the tube, the system allows examination even with the tube being misaligned to the detector position. Hence, it is possible to overshoot the detector by more than 20%. From a clinical point of view, it is highly unlikely for the operator to trigger the examination as the misalignment is visible due to the light field being out of range. AND In very rare cases it may occur that the calculated dose value exceeds the limit of 2 Gy. This may potentially occur only when an organ program for free exposure is selected, and the system uses incorrect (too small) source-to-image distance (SID) for calculatin
