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.

Practice guideline for determinants of image quality in digital mammography |
|
| |
The American College of Radiology will periodically define new practice guidelines and technical standards for radiologic practice to help advance the science of radiology and to improve the quality of service to patients throughout the United States. Existing practice guidelines and technical standards will be reviewed for revision or renewal, as appropriate, |

Pairing service to match display colors |
|
| |
Due to the variation in colors among cold cathode fluorescent lamps (CCFL) used asbacklights, slight differences in color tone between displays are unavoidable. Medical imaging often uses two displays side-by-side, and it is very important that they present the same color tone.

Luminance stabilizing system to provides continuous stable display for medical images |
|
| |
A change in luminance affects gamma characteristics and therefore has adverse effects on diagnostic imaging. TOTOKU medical image displays are equipped with a luminance stabilizing system that automatically compensates for luminance changes due to startup drift, temperature change, and aging.

LED indicator to inform of current status |
|
| |
A glance at the LED indicator tells you the display's current operating status in three distinct colors. When in normal mode (luminance is stabilized), the LED is not lighted to minimize negatively impacting the diagnostic interpretation |

High luminance and long life technology |

Looking at diagnostic images on a high-luminance display is very much like looking at filmed images on a light box. The |

Hardware based pivot function to enable high speed drawing in portrait orientation |
|
| |
The pivot function allows for a 90-degree rotation of the LCD panel into portrait orientation. Unlike other pivoting functions that are implemented using graphics cards and/or that require special software, TOTOKU hardware pivot function is directly implemented in display hardware and thus it is much faster with less noise |

Calibration function to accurately adjust gamma, color temperature, and luminance |
|
| |
Medical image displays are commonly required to display grayscale according to the Grayscale Standard Display Function (GSDF) defined by DICOM Part 14. The calibration function creates the optimum conditions for a medical imaging display by adjusting luminance levels, color temperature, and grayscale characteristics to achieve DICOM GSDF compliant grayscale output. |

Built-in LUT (Look-up Table) to reproduce beautiful grayscale and TOTOKU's technology for simultaneous display of multiple shades |
|
| |
General-purpose displays are capable of 256 shades of gray, but due to unevenness and grayscale discontinuity, they cannot reproduce and display the subtle shading difference required for medical image displays. TOTOKU medical image displays display the most appropriate 256 shades (8bit) out of a maximum of 3826 shades of gray (11.9bits) using the built-in LUT. This technology realizes much finer and smoother grayscale than possible with general-purpose displays.
