Totoku Diagnostic Line (MS55i2)

5MP | 21" Grayscale Display System with LED-backlight

5MP Super High Resolution Display for Mammography

The MS55i2 is equipped with a number of new technologies to deliver higher performance in diagnostic reading.

By adopting the new generation of energy saving IPS panel with LED backlight, MS55i2 has achieved a high contrast ratio of 1200:1, providing brighter and crisper images.

Thanks to the new IPS panel with LED backlight, MS55i2 provides more stability in image quality for a long period of time. Also the new function of DICOM conformance self-test function comes with this digital mammography display.

  • IPS panel with Frontprotection
  • Highest Luminance 1200cd² | High contrast 1200:1
  • 15MP by ISD (Independent Sub-pixels Drive) technology*
  • Luminance Stabilizing System ?-Sentinel
  • Luminance Equalizer ?-Uniformity Congruence
  • DICOM Conformance Self-testing function
  • 5 Years Warranty

Features & Benefits


The MS55i2 is cleared by the US Food and Drug Administration (FDA) for use in standard and multi-frame mammography.
The display can be connected to PM Medivisor (option), a online QA-management service provided through a centralized server.

Independent Sub-pixels Drive (ISD technology)

The MS55i2 is equipped with ISD technology* to accept higher resolution output from modality devices as a major breakthrough. ISD technology provide a resolution of more than 15MP.
*Customized viewer software is required!

DICOM conformance Self-testing function

DICOM conformance test can be easily performed as an OSD function of the display.

Luminance Equalizer ?-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.

Luminance Stabilizing System ?-Sentinel

?-Sentinel consists of a luminance sensor and a luminance control circuit. The luminance sensor is integrated into the front bezel, directly against the screen, and constantly monitors and accurately stabilizes luminance on the screen surface by sending feedback instantaneously to the control circuit. An Ambient light sensor is also built-in so that calibration appropriate for the effects of ambient luminance is carried out.


Standard and multi-frame Digital Mammography.
