1, support for the standard DICOM PART # 14:
A professional medical monitor must support the standard DICOM PART # 14, that is to say, it must have the adjustment of the That is to say, it must have the ability to adjust the DICOM standard curve to match the DICOM standard, so as to ensure the display quality of the image.
2, support for grayscale display:
Grayscale degree is a black and white medical image is a very important feature, which reflects the level of black and white images between the levels of grayscale display requires graphics card support, medical monitors should be equipped with a dedicated graphics card.
Ordinary monitors have: 8 bit - 256 grayscale, used to display color images, no grayscale requirements, the use of ordinary graphics cards;
Medical monitors have: 10 bit - 1024 grayscale, used to display X-ray grayscale images, in the diagnosis of the relevant, the requirements of: 10 bit ~ 11 bit (1024 ~ 2048 grayscale).
3, support for SBC function (stable brightness control):
The brightness of the monitor will decay over time, ordinary monitors due to the lack of stable brightness control and calibration, not only faster decay, usually use, but also due to the impact of the environment, its brightness can not be maintained for a long time in a team of human eyes and the city level, and the professional medical grayscale display Taking into account this problem, the adoption of stable brightness control technology, the display brightness of the feedback information at any time to calibrate, so that it is always maintained above the standard brightness, in line with the clinical reading standards, the requirements of 30,000 or even 100,000 hours of brightness to remain unchanged.
4, resolution:
The number of actual display pixels per unit area, such as 800x600, 1200x1600, etc..
Ordinary monitors have: 1024x768, 1280x1204; basically horizontal display, no need for horizontal/vertical screen conversion;
Medical monitors have: according to the needs of the image, can be horizontal/vertical screen conversion,
1024x1280 (vertical)/1280x1024 (horizontal), known as 1 megapixel (1MP)
1200x1600(Vertical)/1600x1200(Horizontal); called 2 megapixels (2MP), referred to as 1K, commonly used in vertical display, mostly used in CR, DSA, digital gastrointestinal machine, digital gastrointestinal machine, PACS reading workstations;
1536x2048 ( vertical screen)/2048x1536 (horizontal screen); known as 3 megapixels (3MP), referred to as 1.5 K, commonly used vertical screen display, mostly applicable to CCD-DR, PACS diagnostic workstations;
2048x2560 (vertical screen)/2560x2048 (horizontal screen); known as 5 megapixels (5MP), referred to as 2 K, commonly used vertical display, mostly applicable to flat-panel DR, mammography, digital gastrointestinal machine, PACS diagnostic workstations. Flat-panel DR, mammography, PACS diagnostic workstations;
Medical monitor resolution is directly proportional to the price, and the resolution of the radiological equipment is positively correlated with the corresponding equipment should be accompanied by the corresponding resolution of the monitor.
5, certification:
Ordinary monitors have: environmental protection, electromagnetism-related certifications
Medical monitors have: not only environmental protection, electromagnetism-related certifications, and more importantly, the medical industry certification, in order to access to the medical field, recognized by law.
6, safety:
Ordinary monitors have: no LCD screen protection board, power supply for the built-in way no special requirements.
Medical monitors have: due to the requirements of the teaching and the habits of doctors, specially equipped with LCD screen protection board for medical environments with a medical special power supply.
7, graphics cards:
Ordinary monitors have: memory, speed, 3D indicators;
Medical monitors have: display modes, a card with two displays, the main and secondary displays are interchangeable, color - black and white conversion, 10bit grayscale output; horizontal/vertical screen conversion.
