What are the technical requirements of medical endoscopy monitor
With the popularity of digital imaging diagnosis, Medical Monitor has become an important diagnostic tool for radiologists and doctors of related clinical disciplines. With the growing maturity and popularity of PACS technology, as well as the rapid development of various digital imaging devices such as DR, CR, multi-row CT, and 3D images, the purchase and configuration of Medical Monitor has become the focus of attention of hospitals and PACS integrators. Because the medical display is the final rendering of medical images in the digital system, It can replace film, ensure image quality, and finally realize doctors' "soft reading film" observation and diagnosis of patients. In this paper, some problems in clinical application of medical display are reviewed. So what are the technical requirements of a medical display?

一、 Imaging diagnosis must be made by Medical Monitor
Due to the strict requirements of imaging diagnosis on image quality, the Medical Monitor must be used for diagnosis, because the performance of medical display is greatly different from that of ordinary display. Common displays may lead to misdiagnosis or missed diagnosis due to the lack of precision in detail display.
二、Technical requirements of Medical Monitor
High spatial resolution
In order to make the digital image can fully display the specific information of the lesion, it is required that the display has enough pixel value.
High density resolution (fine gray scale)
In order to be able to detect small lesions with small density differences, the display is required to be able to correctly display very small changes in the gray scale.
High brightness
In order to find the subtle structural anomalies of the distortion changes, the display is required to have high resolution and high brightness, which can present the subtle organizational structure to a large extent.
Good image sharpness
In order to detect subtle lesions, the display must have a high degree of sharpness when displaying the tiny image contours.
Brightness uniformity
In order to display subtle differences in the density of objects at appropriate brightness, the display is required to maintain uniform brightness throughout the screen range.
Comply with requirements and equipped with quality control software
To achieve image consistency across multiple monitors, the monitors must be able to calibrate their properties to the grayscale standard by means of calibration operations.
Simplify the display quality control process
Since the display quality characteristics of the Medical Monitor will gradually change as the display ages, in order to maintain a uniform display effect, users are required to control the display quality so as to facilitate the implementation of normal management in the medical environment.
