Recall Action Commencement Date	25/02/2016
Responsible Entity	Emergo Asia Pacific Pty Ltd T/a Emergo Australia
Reason/Issue	Since the introduction of a fix to the measurements algorithm (BZ55214), InteleViewer now uses the ratio of the distance from the source to patient over distance from source to detector to compute a scaling factor to apply to measurements when the Estimated Radiographic Magnification Factor (DICOM (0018,1114)) is not present. That scaling should only be applied when dealing with a projection radiography modality (CR, DX, MG, PX, RF, or XA), however, it ended up being applied to other modalities, such as CT, generating erroneous measurements. This software defect could lead radiologists to base their diagnosis/report on wrong anatomical measurements. No patient incidents have been reported at this time.
