High resolution of 9M sub-pixels realized by ISD
technology

Faithful Reproduction of Image Details
While a pixel pitch of 3MP display is 210µm, MS31i2 achieves 70µm in sub-pixel chain direction by newly developed ISD technology to realize excellent depiction of image details.

Advanced Image Quality with Less Degradation

To display an overall image whose native resolution is higher than the monitor is able to reproduce, the image is converted to a lower resolution image with a certain amount of data loss.
The MS31i2 with high resolution offers excellent image reproduction, faithful to the original captured by the modality device with less image degradation.

ISD (Independent Sub-pixel Drive) Technology
Driven by each sub-pixel value corresponding to detailed information recorded in an original image, three times resolution enhancement is achieved. (Patent pending) In addition, up to 1276 shades of gray are now simultaneously displayable by the upgraded ISD technology.

*Customized viewer software is required to display images with enhanced resolution by the ISD technology.

3MP-based display with the ISD technology performs either equaling or surpassing the 5MP's Comparison between 9 MsP and 5 MP Visibility comparison Visibility comparison of existence and shape evaluation of microcalcifications (MCLs), using 50 clinical cases obtained by a digital mammography system (pixel size: 70um). Scoring method for 9MsP superiority The most of cases were rated as "Equivalent", and 23% were answered as "Better". Our study indicated that the potential performance of the 9MsP LCD was equivalent to or better than the conventional 5MP LCD for evaluating very small MCLs and interpreting clinical digital mammography with various types of MCLs. Note: Display magnification % was adjusted freely by each observer.

Special AR Coating for Film-like Black and Improved Sharpness

TOTOKU's new special AR coating technology addresses properties of focus, noise reduction, contrast, and viewing angle achieving film-like black and accurate reproduction of images. (Patent pending)

Simultaneous display of 1276 shades of gray

Realizes smoother grayscale display required for medical image displays. 

New luminance stabilizing system λ-Sentinel II

λ-Sentinel II consists of a luminance sensor and luminance control circuit. The luminance sensor, integrated into the front bezel, consistently monitors and accurately stabilizes luminance on the screen by rapidly communicating with the backlight sensor.
In addition, a build-in luminance sensor provided with i2 models enables even simpler calibration without attaching the calibration sensor.

Remote grayscale check and remote calibration functions

Conformance testing to DICOM GSDF and calibration can be remotely accomplished. These features minimize the burden on display administrators.

* Optional PM Medivisor software is required.

Luminance equalizer λ-Uniformity Congruence

Is built in to achieve highly accurate luminance uniformity across the screen. Luminance unevenness is minimized in the final tune-up prior to shipping.
* Images shown are for illustrative purposes only.

Calibration function

Calibrates luminance and gamma to enable smooth grayscale display that is faithful to DICOM GSDF.
* Optional calibration kit is required.

Hardware pivot function for fast drawing in portrait on landscape orientation

Stress-free operation is made possible by fast drawing speed for on-the-fly change to portrait.

OSD Information Display

With a push of a button, the display's current status can be checked such as the display model, total operating time, actual measurement of luminance, and calibration settings.

LED indicator to inform of current status

A glance at the LED indicator tells you the display's current operating status.

Enhanced convenience with utility software:

Advanced power saving*

The backlight dims as the screensaver starts, reducing power consumption and preventing unnecessary deterioration of the backlight.
* This feature may not be available, depending on the specifications of the graphics card used.

Gamma check

18 points of luminance values are measured and plotted into a graph.

Ambient light and display luminance measurement

The built-in sensors measure display luminance and ambient illuminance.

Pairing service to match colors of two displays (Optional)

 

 

Worldwide medical safety standards

This display is certified under various medical safety standards that are much more demanding than those for general-purpose IT equipment.
