- RadiForce GS521
Featuring high definition, a high resolution, and the capability of rendering 15 mega sub-pixels, the RadiForce GS521 is designed specifically for displaying digital mammography images. It comes in a choice of glare panels to meet the needs of its usage environment.
High-Resolution

“Information volume” of a digital mammography image should exceed 5 million pixels. When a lower resolution monitor displays this “Information volume”, the monitor stretches the information forcing the mosaic to appear as shadings. With a 2048 x 2560 resolution or 5.24 million pixels, the stretching effect is minimized and the mosaic becomes suitable for rendering subtle masses and calcifications, within the mammography image.
High-Definition and High-Density

0.165mm pixel size is the smallest pixel size among current EIZO medical monitors providing high-definition and high-density display without shadings appearing granular.
12-Bit Simultaneous Grayscale Display

Along with EIZO’s new frame rate control technology (patent pending), 4,096 (12-bit) grayscale tones can be displayed simultaneously from an abundant palette of 13,771 tones for high-definition digital mammography.
12-bit graphics board and 12-bit viewer software needed for 12-bit display.
Graphics board VREngine SMD5-PCI recommended for 12-bit display.
Brightness Uniformity
The Digital Uniformity Equalizer (DUE) function provides optimum backlight luminance uniformity which is considered difficult to attain due to the characteristics of LCD monitors.
Distinctive Glare Panel
With a distinctive glare panel, there is no diffused reflection by the waffled surface, and the outline of the image is displayed more clearly. Therefore, the subtle images such as calcification and masses will be easier to observe reducing the strain on the observer.
Please note that the reflection of surrounding light may increase when used in a bright environment.
Available with either a glare panel or anti-glare panel.
Sharper Image Outline
MTF (Modulation Transfer Function) is a parameter to define the display sharpness and resolution of a monitor panel. The glare panel has better MTF characteristics than the anti-glare panel meaning the glare panel can be expected to display the outline of a detailed image more sharply.
Brightness Stabilization
At startup or upon wakeup, the EIZO patented drift correction function quickly stabilizes the brightness level. In addition, a sensor measures the backlight brightness and compensates for brightness fluctuations caused by the ambient temperature and the passage of time.
This brightness stabilization function is EIZO patented technology (Japan patent numbers 3171808 and 3193315, US patent number 6188380).
15 Mega Sub-Pixels Display
The GS521 comes with a Sub-Pixel Drive (SPD) function capable of displaying 2048 × 7680 super high resolution by controlling each sub-pixel separately. With a 15 mega sub-pixels (MsP), sufficient information volume of the original medical image will be displayed, making the monitor suitable for rendering the outline of a detailed digital mammography image more sharply.
15MsP viewer software needed for 15MsP display.
10-bit simultaneous display supported when displaying 15MsP.
DICOM Part 14 Compliant
To ensure the most accurate and consistent shadings possible, EIZO carefully measures and sets every grayscale tones on the production line to produce a monitor compliant with DICOM Part 14.
DICOM Part 14 Calibration
When the self-diagnosis function, utilized with bundled RadiCS LE quality control software, detects a change in luminance, a warning icon appears on the desktop taskbar enabling prompt correction. Furthermore, the self-calibration function, a simplified calibration compliant with the DICOM Part 14 standard, can periodically be performed to correct the grayscale tones and brightness of the monitor.
Backlight Saver with Screen Saver
With ScreenManager Pro for Medical utility software installed, the Backlight Saver function turns off the monitor’s backlight when the screen saver is activated, and turns it on again when the computer comes out of screen saver mode. This function helps to reduce power consumption when the monitor is used for a prolonged period of time.
Backlight Saver with Viewer Application
By setting the Backlight Saver function to operate with viewer application, the monitor’s backlight is on while the viewer is being used and the backlight is off while the viewer is not being used.
Calibration Mode Selection
Selectable with the front panel buttons, the CAL Switch function allows for various calibration modes of different modalities such as digital mammography, ultrasound, and MRI images. Furthermore, with ScreenManager Pro for Medical installed, auto mode settings can be made with the Auto CAL Switch function.
Dual Link
With dual link input support, monitors achieve a clock frequency of 50 Hz even when displaying a QSXGA (2048 × 2560) resolution. This enables reproduction of smooth moving pictures with minimum dropping of frames.
Graphics board with dual link compatibility required.
Compatibility with Various Graphics Boards
Supports various input signals for compatibility with a wide range of graphics boards so the user can select the board according to budget and performance requirements. This includes single link, dual link, as well as packed-pixel signal.
DisplayPort Connectivity
Next-generation DisplayPort connectivity allows a large volume of information transmitted at once, which means the monitor can more easily adapt to high resolution or multi-grayscale display.
DisplayPort cable sold separately.
Pairing Monitors
EIZO offers the same color and grayscale for two monitors bundled as a pair in one box.
Clear Base and Blue Base Backlights
Available with either a clear base or blue base backlight.
Brightness Stability Within Usage Time Guaranteed
EIZO’s confidence in its product quality extends to brightness stability which is also covered during the usage time specified in the warranty.
Medical Standards
Compliance with stringent medical, safety, and EMC emissions standards including EN60601-1 and UL60601-1.
5 Year Warranty
EIZO and its authorized distributors offer a five-year limited warranty.
Digital Mammography Monitor Quality Control Standards Compliance
EIZO’s easy-to-use RadiCS UX1 quality control tool (sold separately) performs precise calibration conforming to DICOM Part 14 and enables quality control complying with ACR Practice Guideline and other QC standard for digital mammography monitors.
QC Standards for Digital Mammography Monitor
Presence Sensor for Convenience
Once attached to the top of the monitor the Clip-On Swing Sensor (sold separately) can remain in place and is ready for use. This saves the time and trouble of attaching and removing it when performing quality control tasks.
