Today I will add some knowledge about the flat panel detector. In the previous article, it was mentioned that the flat panel detector is a kind of sophisticated and expensive equipment, which plays a decisive role in the imaging quality. You are familiar with the performance indicators of the detector. Help improve imaging quality and reduce X-ray radiation dose.
Digital Radiography (DR) is a new X-ray photography technology developed in the 1990s. With its significant advantages such as faster imaging speed, more convenient operation, and higher imaging resolution, it has become The leading direction of digital X-ray photography technology has been recognized by clinical institutions and imaging experts all over the world.
The core of DR technology is flat-panel detector. Flat-panel detector is a kind of precise and precious equipment, which plays a decisive role in imaging quality. Familiar with the performance index of detector will help us improve imaging quality and reduce X-ray radiation dose.
The flat panel detector is composed of a shell (protective layer), a fluorescent layer, a circuit board, and a heat sink. The fluorescent layer is divided into CSI and GDS (GDOS0). The phosphor layer of CSI displays clearer images, and the phosphor screen of GDS has higher sensitivity.
According to semiconductor materials, it can be divided into amorphous selenium flat panel detectors and amorphous silicon flat panel detectors. Amorphous selenium flat panel detectors have higher sensitivity and are usually used for dynamic plates.
According to the classification of image software, there can be medical software, veterinary software and industrial software.
Pay attention to the use of flat panel detectors. The most suitable temperature for the flat panel working environment is 5° to 35°. If it is used in tropical areas, it is necessary to do a good job of cold control. At the same time, pay attention to the etching effect. The theoretical life of the flat-panel detector is 3 years. The flat-panel detector that is used for a long time will produce artifacts that cannot be eliminated due to the etching effect, which will affect the quality of the image. The above is the information of the flat panel detectors supplemented today.
