What are the main parameters of the P6 articulation endoscope? Grayscale, the human eye's response to grayscale is not linear. Our eyes are less responsive to the dark parts than the bright parts. In order to achieve a good reproduction of black and white images with continuous grayscale, a graphics card with a grayscale output of more than 10bit should be selected. Brightness, the higher the brightness, the more gray scales the human eye can distinguish. To improve grayscale resolution, the P6 articulation endoscope has a higher brightness. The higher the brightness, the more gray levels the human eye can distinguish.
What are the main parameters of the P6 articulation endoscope?
P6 articulation endoscope resolution, resolution refers to the number of display pixels per unit area, and the cost of the display is also proportional to the resolution. Choose a normal monitor resolution of 1024×768. The resolution of the monitor is closely related to the resolution of the image itself. Proper selection of the resolution of the monitor can effectively reduce the acquisition cost of the monitor.
Response time, the response time refers to the response speed of the liquid crystal display to the input signal, that is, the response time of the liquid crystal from bright to dark. At present, the size of the display screen used in the display of medical imaging equipment is mainly 19-33 inches. The resolution of mainstream products is still 2MP and 3MP, and the resolution is lower. With the increase in demand for higher resolution and higher quality medical diagnostic images , the hospital's demand for 5MP, 6MP diagnosis P6 articulation endoscope is also increasing. Due to the different application fields of medical monitors and ordinary monitors, the technical requirements of the parameters are also different. The following is a comparison and description based on the main parameters.
P6 articulation endoscope size is expressed in diagonal length. The mainstream sizes of ordinary monitors are 15" and 17", and the size is basically proportional to the price. The larger the size, the higher the price; the common sizes of medical monitors are 18", 20", and 21". price related.
Resolution: The actual number of pixels displayed per unit area, such as 800600, 12001600, etc. The resolution of medical displays is proportional to the price, and positively related to the resolution of radiological equipment. The corresponding equipment should be equipped with displays with corresponding resolutions.
Brightness: Ordinary displays have: 200-300cd/m2 without constant brightness requirements; medical displays have: 600-700cd/m2 brightness set between 400-500cd/m2 after calibration; requires 30,000 hours or even 100,000 hours of brightness The value remains the same.
P6 articulation endoscope contrast ratio: expresses the ratio of the display to the bright value and the dark value. The color display does not require too much, and the medical display requires it to express the degree between black and white of the grayscale image. Common monitors are: 300:1~400:1; medical monitors are: 600:1~1000:1. Grayscale: Grayscale display requires graphics card support, and medical monitors should be equipped with dedicated graphics cards. Common monitors include: 8bit-256 grayscale, used to display color images, no grayscale requirements, use ordinary graphics cards; medical monitors: 10bit-1024 grayscale, used to display X-ray grayscale images, related to diagnosis, requires ≥ 10bit~12bit (1024~4096 grayscale).
The size of the monitor, the size of the medical monitor is related to the resolution. The higher the resolution, the larger the size, but it is not proportional. CRT monitors range in size from 17 inches to 21 inches. Liquid crystal (LCD) displays range in size from 18 inches to 32 inches.
Horizontal screen and vertical screen. Regarding the P6 articulation endoscope, it is a question of choosing a horizontal screen or a vertical screen. You can choose according to your own habits. Today's medical LCD manufacturers have designed a function that can be converted between horizontal and vertical, which greatly facilitates clinical use, taking into account the habits and requirements of doctors to read pictures.
