The medical network on July 6, 3-4 years ago, the dynamic DR was not known; Today, dynamic DR is a hit in the medical world. Today, there is no need to discuss the huge role and contribution of dynamic DR to clinical application. Today, dynamic DR is not only the credit of marketing. Marketing can promote product promotion, but marketing can't solve the problem of core customer demand. Dynamic DR is a good model product to meet demand and marketing.
However, the problem is that as a durable industrial product, the procurement frequency of dynamic DR is very low for a single purchasing unit, so the user's ability to identify dynamic DR is limited. That's right, there are a lot of fake dynamic DR on the market.
At present, there are two kinds of false dynamic.
The first: a combination of tablet detector and digital gastrointestinal machine.
Some people in the industry call this the "tablet dynamic DR", which is very easy to mistake for the dynamic DR. This kind of product, on the surface, the function is complete, can make the film, the perspective, the gastroenteric, the contrast, but has a huge problem namely: instantaneous high count piece. The combined gastroenteric machine USES the image enhancer perspective and then images the plate probe by the motor. This process, currently the best technology in the market, takes more than 2 seconds, which is clearly not comparable to the real dynamic DR.
The basic reason for a combined-type gastrointestinal machine is that there are many similarities between the two, and they are easily confused. For example, if you don't ask for a time, then both are the same.
The second, small size of the flat panel detector composed of a flat stomach.
The flat-panel gastroenteric machine, consisting of a small, fluoroscopic tablet detector, is the closest thing to the dynamic DR, but why can't it be called dynamic DR? The reason is simple, because such products have major flaws in clinical trials. It is mainly reflected in: 1. The perspective is small, such as 14inch * 14inch, 12inch * 12inch, 9inch * 9inch. This size can not cover the examination site in a variety of imaging examinations, resulting in misdiagnosis and misdiagnosis. The pixels are low, the irregular size, and the pixels are only 6.4 million (14inch), 4.7 million (12inch), and 2.6 million (9inch).
When purchasing equipment for medical institutions, it is best to purchase the most suitable equipment according to your own needs. As the most advanced equipment in the industry, dynamic DR has more and more user choices. Then, when choosing, make sure that the purchased product is the real dynamic DR. For the convenience of screening, there is a simple criterion for dynamic DR in the industry, namely:
