Modern medical technology enables complex examinations. But in the end, it is the radiologist who is responsible for fast and accurate diagnostic findings. To support these findings in a soft copy reading environment, flat-panel displays need to comply with the highest visual requirements. Their image quality has a decisive influence on diagnostic accuracy. MultiSync MD Series grayscale displays - in combination with the appropriate graphics controller - are designed for diagnostic imaging and for use in Picture Archiving and Communication System (PACS) applications. Furthermore, diagnostic imaging displays from NEC Display Solutions are based on technologies and functions which actively contribute to a reduction of cost of ownership.

Using stateof-the-art equipment during production, each NEC MultiSync MD Series monitor is calibrated to the DICOM display function for luminance and to a desired whitepoint (color of the white). NEC Display Solutions' patent-pending X-LightTM technology (Fig. 1) has the unique ability to control and adjust the luminance and whitepoint via an integrated fast-feedback internal backlight sensor, which continuously monitors and realigns these settings to maintain the factory calibration throughout the life of the monitor. X-Light technology also alleviates the color shift of the backlight to the yellow spectrum. Monitor matching and reduced downtime. X-Light helps reduce service costs as it enables a more flexible use of display equipment. Since all X-Light-equipped monitors are set for the same whitepoint during production, they can be exchanged at any time within one location and swapped in existing dual- or multi-screen configurations without calibration. Standalone calibration and monitor matching. NEC MultiSync MD Series monitors have been designed to maintain their fac- tory calibration. However, if calibration or matching (Fig. 2) to a replacement is required, the monitors can be configured using the built-in, standalone algorithm programmed into the monitor's firmware. This feature is useful for monitors that are not used in a setup where calibration can easily be performed with a PC and external software or non-supported operating systems. Figure 2. USB GammaComp™ MD calibration and conformance software. Quality control and calibration/matching can also be accomplished using GammaComp MD (shipped with display), ensuring consistent image quality on a single display system. The software maintains the monitor's conformance to the DICOM standard, while providing an easy-to-use QA environment for medical imaging. Optionally, GammaComp MD Administrator provides centralized control and management of multiple display systems.
