3MP-based Display for Digital Mammography
Digital mammography viewing demands an extraordinarily high level of precision
from your LCD display. Totoku's MS31i2 redefines new standards of care by over-delivering
resolution and clarity for improved accuracy in breast cancer screening.
integrated ISD (Independent Sub-pixel Drive) technology, the MS31i2 exceeds
resolution values of traditional 5 Mega-pixel displays, and due to economies
of scale, is more affordable than its 5 megapixel counterpart. Introducing
the MS31i2, with ISD technology enables a 3Mega-pixel-based LCD to render 9
mega sub-pixel images, exceeding the current standards of care for primary
mammography diagnosis. The MS31i2 is FDA (510K) cleared for the use of Digital
High resolution of 9M sub-pixels realized by ISD
Faithful Reproduction of Image Details
While a pixel pitch of 3MP display is 210µm,
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.

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
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.

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
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
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.
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.
