Features & Benefits


The Coronis 3MP grayscale display offers highest performance in picture quality while calibrated to 600cd/m2 and stabilized by the BLOS technology throughout its entire lifetime. The built in system for uniformity correction allows enhanced diagnostic precision with the luminance spread envenly over the full screen surface. Ambient Light Compensation guarantees stable diagnostic conditions.


BLOS is the Backlight Output Stabilization technology, which inside the Nio Line allows the use of the displays for a wide range of medical imaging applications. BLOS guarantees fast power-up and continuously stabilizes the luminance output of the LCD’s backlight to make sure that there is no change in your diagnostic confidence for the time of entire use of the product. This significantly improves the overall optical efficiency of your Nio display system and provides long-term image stability.

Uniformity Correction

As todays LCD Technology is still suffering from non-uniform behavior across the screen Barco has developed the Uniform Luminance Correctioon Technology to compensate this negative effect.  This is the reason why we can guarantee DICOM compliance across the entire display area. To avoid false interpreted medical  images due to non uniformity this technology is a key feature of todays high end medical displays as they are delivered under the brand of Barco.

Ambient Light Compensation

The Ambient Light Compensation (ALC) is another important feature of the Coronis products. The diagnostic competence is very much influenced in a very negative way by changing ambient light conditions in the reading room. To compensate this the ALC was developed. This systems measures the ambient luminance and compares it to preset thresholds that characterize the reading room. A notification to the QA administrator can be done and the DICOM curve can be corrected in realtime.


The Coronis 3MP is a high-grade grayscale display system with a resolution of 2048 x 1536, and can be used in different medical applications for primary diagnosis. Beside PACS networks the display is used in dedicated imaging solutions such as Chest radiology, CT, MRI, X-Ray, angiography and orthopedic imaging. Barco's high-bright LED backlights render more Just Noticeable Differences to help you see more shades of gray. By making subtle details more noticeable more quickly, Coronis 3MP LED reduces windowing and leveling time so you can read your studies more efficiently.
