Monochrome Display Developed for Mammography Diagnosis

Siemens Automation and Drives (A&D; Nuremburg, Germany) has developed the new SMD 21510 D 5-megapixel display for medical applications requiring outstanding picture quality. The integrated fully automated stability system ensures reliably verified grayscale response and continuous luminance levels. The new medical display can be used with a number of standard or high performance graphic cards of the latest generation.

The high-resolution monitor has 2048 x 2560 pixels and a luminance of 750 cd/m2 (candelas per square meter). Two independently functional sensors are used to continuously monitor the luminance and grayscale levels. The integrated stability sensor (ISS) monitors the backlight at the center of the display while the integrated consistency sensor (ICS) reviews performance on the front right corner without obstructing the user's view of the display. This redundant monitoring system ensures consistently high image quality and conformance with medical imaging standards such as DICOM (Digital Imaging and Communications in Medicine). The blue-tinted CCFL (cold cathode fluorescent lamp) backlight is optimally suited to the human visual system, which is especially sensitive to light in this color range. This enables diagnoses with maximum sharpness and minimum eye fatigue.

The display's grayscale display is delivered pre-calibrated and is therefore ready for use immediately out of the box. With five preset 12-bit LUTs (look-up tables), the monitor can be installed quickly and easily, and can also be adapted to difficult lighting environments. The monitor data are stored in the LUTs, thus making it possible to use almost any graphic card. The new display controller electronics supports both eight-bit and 10-bit digital visual interface (DVI) input signals, thereby opening up a large selection of graphic cards and making the display well suited for use in complex applications. With the quality software, SMfit, and external photometers, the display's settings can be customized to the local environment, the luminance values can be measured, and if necessary, the internal sensors can be readjusted to their optimal levels.

In June 2007, the Eizo Nanao Corp. (Hakusan, Japan) and Siemens A&D reached an agreement on the purchase of Siemens medical monitors business. The transaction is subject to approval by the responsible authorities and is scheduled for completion later in 2007.
