The products, when deployed with centricity pacs and centricity enterprise archive, or retrieving images from vendor neutral dicom archives, display inaccurate measurements on magnification views acquired from certain digital x-ray systems because certain scanner-originated magnification factors are not taken into account by universal viewer. specifically, distance measurements may not be calculated accurately when viewing projection radiography and fluoroscopy images that contain values in the imager pixel spacing (0018, 1164) and magnification factor (0018, 1114) dicom tags but does not contain a value in the pixel spacing (0028, 0030) tag. true size printing on film/paper for images produced by such modalities is also impacted. if known size fiducials are not present on the image and manual calibration is not possible, this can lead to an overestimation of distance measurements on the images. there have been no injuries reported as a result of this issue.

For all projection X-rays, GE Healthcare recommends that the user perform the necessary measurements on the standard contact images, and not rely on measurements made on the magnified views unless the measurements have been independently verified for each X-Ray machine installed or manually calibrated using a radio-opaque fiducial of a known size. Attention should be given to prior cases acquired previously as they may be affected by the safety issue. GE Healthcare will correct all affected products.
