The DR market will enter a development platform period in the future
DR equipment, also known as direct digital X-ray photography system, is composed of electronic cassette, scanning controller, system controller, image monitor, etc. It directly converts X-ray photons into digital images through electronic cassette, and is a generalized direct digital X-ray photography. In a narrow sense, direct digital radiography, also known as DDR, usually refers to digital radiography using image conversion technology using flat panel detectors, and is a true direct digital X-ray photography system. Ordinary X-ray machines have gone through the development process from film machines, CR, CCD-DR to flat DR.

Is dynamic DR difficult to distinguish between true and false? Static DR is about to end?
After the birth of CT in 1971, there was a wave of image digitization. In 1979, the DR system for flying point scanning emerged. At the RSNA North American Radiological Society's product exhibition in 1980, DR exhibits attracted worldwide attention. Subsequently, various countries competed to develop DR systems and detectors, and launched many practical DR devices. Compared to traditional X-ray machines, DR has the characteristics of clearer images, lower radiation, and faster examination speed. With the development of technology, dynamic DR has emerged in recent years, greatly reducing the rate of missed diagnosis and misdiagnosis. However, many grassroots hospitals have also reported buying fake dynamic DRs. Today, the editor will come to popularize what is truly dynamic DR.
