Clinical selection method of medical monitor
medical monitor and high - resolution and high - brightness display used in the medical industry. With the increasing maturity and popularity of PACS technology, and the rapid development of various digital imaging equipment such as DR, CR, multi-row CT, 3D image, etc., the selection and configuration of medical monitor has become the focus of attention of hospitals and PACS integrators. The following introduces the clinical selection method of medical monitor.

High resolution display and achieve fine grayscale shadow display
When choosing the display brand and model, the main consideration should be the information content of the medical image to be displayed. Because of the high precision of digital image mammography, mammography is taken as an example. It is estimated that the "information content" of a digital mammogram should be more than 5 million pixels (5MP). Displaying this information with a display with a low pixel value results in an unrealistic representation of the information (the Mosaic image appears as a shadow). With a 2048×2560 resolution or 5.24 million pixels display, this unreal display effect will be controlled to a low degree. In mammography, a Mosaic image can show tiny lumps and calcifications that can lead to misdiagnosis.
High resolution, high brightness and minimal pixels
The 0.165mm pixel size is the smallest of the current medical imaging professional display products, it provides high resolution and high brightness images, and does not allow the shadow display to be granular.
Luminance uniformity and stability
In order to maintain the consistency of the image display, the display of breast image requires uniform brightness. However, DUE to the characteristics of liquid crystal display itself, the backlight tube is difficult to reach a consistent brightness, the experiment proved that the professional display with the digital uniform equalizer (DUE) function can provide high brightness uniformity of the image.
Brightness stability
Displays with drift correction can quickly stabilize brightness levels when switched on or when the display is awakened from sleep. In addition, sensors can be used to measure the backlight brightness of the LCD and compensate for any brightness fluctuations caused by ambient brightness changes and prolonged use.
