Brivo OEC 715/785/865 Mobile C-Arm X-Ray Product also provides the feature of Auto-Adaptive
Non-uniformity Correction to improve the uniformity of the image. Because of the curved nature of the
image intensifier tube, less X-Ray energy is received at the periphery of the tube than at the center. This
causes the image to appear darker around the image edge. Auto-Adaptive Non-uniformity Correction is
used to correct it and improve the uniformity of the image.
Correction template can be created automatically in service mode by service engineer, and
NOTE
then the images in live mode can be corrected with the template in real time. This feature is
not user selectable.
