QUBYX Integrated PEHAMED Meters in Medical Monitor QA Tool

April 25, 2012

11/22/2011, Nice, France – QUBYX, a technology contributor to medical imaging and color management industries, today announced that it has integrated digital luminance meters CD-Mon and CD-Lux by PEHA Medical Equipment GmbH, designed to perform acceptance and constancy tests on medical monitors, in PerfectLum 3.0 medical display quality control application. Now PerfectLum supports even more models of measurement devices.

PEHAMED CD-Mon and CD-Lux are digital luminance meters, designed to perform acceptance and constancy tests on image displays devices, such as monitors, screens or image display units according to DIN V 6868-57, and on viewing devices according to DIN 6856. These high-end sensors measure luminance, including the influence of ambient light, on medical imaging devices.

With PerfectLum 3.0 DICOM calibration application, PEHAMED luminance meters can now be used not only for acceptance and constancy tests, but also for DICOM calibration. In this way, functionality of CD-Mon and CD-Lux is considerably enriched, allowing not only conformance of imaging quality to medical standards, but enhancement of imaging precision as required by these standards.

“We are happy to integrate high-quality Pehamed measurement devices in our software,” says Marc Leppla, Director of QUBYX. “ We believe these professional devices together with our medical monitor calibration software will provide a high-end product to impress QUBYX and PEHAMED customers.”

PEHAMED will demonstrate PerfectLum with its luminance meters CD-Mon and CD-Lux at RSNA 2011 in Chicago. Visitors are welcome at PEHAMED booth 6202 in Hall A (the South Building).


The PEHA Medical Equipment GmbH, a dynamic company with operations around the world, was founded in 1975 and is located in Sulzbach (Taunus) in Hesse, Germany. The company develops, produces and sells measurement and test instruments for quality assurance in medical X-ray as well as X-ray accessories.

Why PerfectLum?

Extremely precise calibration

The medical display calibration software performs calibration on all shades of gray, achieving neutral gray shades and the lowest Delta E values. It also adjusts the white point to the desired target value in candelas, defined in preferences. This ensures that the observer sees colors correctly, as the aspect of an image is influenced by colors in the grays, not just luminance.

Conformance to international standards

PerfectLum medical display calibration tool performs DICOM part 14 GSDF, CIE L* and Gamma calibrations to ensure that a display conforms to most demanding requirements. PerfectLum DICOM calibration guarantees quality of images for diagnostic images professionals, and thus ensures accuracy of diagnosis.

Standardized quality control

PerfectLum Suite medical monitor QA tool performs acceptance and constancy tests to AAPM TG18, DIN 6868-57, new DIN 6868-157 Norm-Entwurf, JESRA X-0093, and IEC 62563-1, making the test procedure as simple as possible. Medical display quality assurance becomes easier than ever.

Easy and centralized display management

With PerfectLum Remote display management system, an unlimited number of displays in multiple healthcare facilities can be controlled remotely. No need to visit each clinic for quality assurance procedures – every test can be run remotely from the server!

Tremendous cost savings

The combination of PerfectLum medical monitor calibration and QA tool and a quality consumer display can outperform most expensive displays on the medical market, and also save thousands of dollars. While the average total price for a commercial display and PerfectLum bundle would make less than 2.000 USD, the average sales price for similar 4mp medical-grade monitors is approximately 6.900 USD. This enables hospitals, utilizing hundreds of such displays for diagnostics and reviewing of medical images, to make enormous cost savings of up to 300%.
