EIZO Unveils World's First Monitor to Simultaneously Display Color and Monochrome Images with Separate Gamma Curves

RadiForceRX430Hakusan, Japan September 1, 2010 – Eizo Nanao Corporation ("EIZO") today announced it will unveil the 29.8-inch RadiForce RX430 at RSNA 2010. The RX430 features a Hybrid Gamma function that makes it the world's first* monitor capable of simultaneously displaying monochrome and color images with their own gamma curves. Hybrid Gamma automatically distinguishes whether the displayed images are monochrome or color even within the same application. It displays the monochrome images in DICOM Part 14 adjusted mode and the color images in gamma 2.2 adjusted mode. These and other modes are user selectable. This expands the usability of PACS (Picture Archiving and Communication System) applications by ensuring that color and monochrome medical images are optimally displayed.


The screen size and native resolution of 4 megapixels (2560 x 1600) for a 16:10 widescreen format give this monitor the same amount of screen size and number of pixels as two 2 megapixel monitors in portrait mode but without the obtrusive bezels. This simplifies comparing images or allows for showing more information within one screen.


The RadiForce RX430 utilizes a new IPS (in-plane switching) panel with almost no noticeable color shift when viewing the screen from oblique angles. It offers a maximum brightness of 1,000 cd/m² and 1100:1 contrast ratio. This figure is on a par with monochrome monitors, making the RX430 ideal for displaying both 3D rendering and fusion color images and CT (computed tomography) and MRI (magnetic resonance imaging) monochrome images compliant with the DICOM (Digital Imaging and Communications in Medicine) Part 14 standard.


Like all RadiForce diagnostic monitors, the grayscale tones for each RadiForce RX430 unit are adjusted at the factory to comply with DICOM Part 14. Furthermore, they are calibration compliant with the DICOM Part 14 to ensure continuing monitor quality control.


The RadiForce RX430 supports an Integrated Front Sensor housed within the front bezel to provide independent verification measurement of the grayscale tones and to perform calibration compliant to DICOM Part 14. By installing the bundled RadiCS LE software, the Integrated Front Sensor and RadiCS SelfQC function allows QC tasks to be performed by the monitor itself even when the connected workstation is switched off. This dramatically cuts monitor quality control workload and maintenance costs.


It also comes with an integrated presence sensor that offers convenience and energy savings. The presence sensor will prompt the monitor to switch to power save mode when it detects the user is away from the monitor and then resume normal operation when the user returns. Furthermore, the sensor determines whether to start QC tasks such as calibration at scheduled times. If the user is working, the task stays in stand-by mode, and when the user is away from the monitor the task is performed.


In addition to its versatility for diagnostic use, the RadiForce RX430 can be used for viewing images in operating rooms. To meet the need of different OR environments, this monitor is available in two model configurations: a standard configuration that comes with a stand but without a panel protector, and a free mount (no stand) configuration that comes with a panel protector and offers easy attachment to ceiling suspensions. Its sealed cabinet design with no ventilation holes on top is ideal for safe and clean integration in the OR and the free mount model with a panel protector is IPx2-rated to protect against ingress by dripping water.

With the CAL Switch function the grayscale tones and brightness settings are stored directly in the monitor, allowing one to easily adapt to different modality images such as CR (computed radiography), CT, and endoscopy by selecting the desired modes through the button on the front bezel. The RX430 includes Text mode for clinical records, sRGB mode for endoscopy, Hybrid Gamma mode for hybrid display of monochrome and color images, and five variant Calibration modes for convenience that eliminate the need to perform calibration each time a new grayscale and brightness setting is required.



Mass production of the RadiForce RX430 is scheduled for January of 2011. Availability varies by country so please contact the EIZO subsidiary or distributor in your country for details. Visitors to the EIZO booth #4203 at RSNA (Radiological Society of North America) 2010 in Chicago, Illinois, USA can have a first look at the RX430.
