  • Notas adicionales en la data
    According to manufacturer if references of known size are not present in the image and manual calibration is not possible, this may lead to an exaggerated estimation of the measurements of distances in the images. Incorrect measurement of distances can lead to misinterpretation of images, which are used as the sole or main basis for planning or retaining an intervention. However, some measurements may be outside the physiological range or independently verified, which will cause the measurement discrepancy to be detectable. ### Update of the field action: UPDATED ON 10/23/2017, the company presented the report of completion of the field action proving the sending of the safety notice to the client with evidence of science and all actions completed.
  • Causa
    According to record holder information, a security issue has been identified with either the centricity pacs and centricity enterprise archive products or the retrieval of dicom file images from a neutral vendor, which may display inaccurate measurements of extended views acquired from digital x-ray systems . this failure occurs because certain scanner magnification factors are not considered by universal viewer. more specifically, distance measurements may not be accurately calculated when viewing projected radiographs and fluoroscopy images, which contain imager pixel spacing (0018, 1164) and magnification factor ] (0018, 1114) in the dicom header, but does not contain pixel spacing values ​​(0028, 0030). full-size film / paper printing of images produced by modes is also impacted by this security problem.
  • Acción
    Software update. The company's recommendations are that for all projection X-rays, users must perform the necessary measurements on the standard contact images and not rely on the measurements made in the magnified view unless the measurements of each X-ray equipment have been checked independently or manually calibrated using a radiopaque reference of a known size. In addition, users should pay attention to cases acquired prior to the application of these safety instructions in the urgent security warning (attached to this form), as these cases may be affected by the security problem.
