The ME551i2 digital mammography LCD monitor from Totoku has a 21.3-inch, 5 megapixel DICOM-calibrated diagnostic display with an 11.9-bit grayscale palette and 750 cd/m2 brightness. Furthermore, it has a luminance equalizer to achieve highly accurate luminance uniformity across the screen and the capability to simultaneously display 2,048 shades of gray (11-bit) to realize smoother and precise grayscale display.
Another notable characteristic of ME551i2 is the display accuracy control capability. The built-in luminance sensor is mounted in front of the screen and monitors luminance constantly to accurately stabilize luminance. An optional performance monitoring software further enables the easy evaluation of DICOM GSDF conformance based on the data measured by the front sensor.
