Digital x ray flat panel detectorThe digital x ray flat panel detector is a kind of sophisticated and expensive equipment, which plays a decisive role in the image quality. Familiar with the performance indicators of the detector can help improve the image quality and reduce the X-ray radiation dose.
Digital x ray flat panel detector (Digital Radiography, DR for short) is a new X-ray photography technology developed in the 1990s. It has significant advantages such as faster imaging speed, more convenient operation, and higher imaging resolution. , Has become the leading direction of digital X-ray photography technology, and has been recognized by clinical institutions and imaging experts all over the world.
At present, most X-ray machines are equipped with a DR imaging system, and the core of DR technology is a flat panel detector. The use of a digital x ray flat panel detector can make the image quality clearer.
According to the material, the digital x ray flat panel detector can be divided into two types: amorphous silicon and amorphous selenium. The traditional Chinese medicine practitioner will choose the DR of different types of flat panel detectors according to different inspection parts. For chest examination, the focus will be on observing and distinguishing the density of different tissues, so the density resolution requirements are relatively high. In this case, it is advisable to use the DR of the amorphous silicon flat-panel detector, so that it is easy to obtain a higher degree of comparison of the image, which is more helpful for diagnosis; for the inspection of the limbs, joints, and breast, it is necessary to have a higher level of detail. The imaging of selenium has high requirements for spatial resolution, so DR of amorphous selenium flat-panel detectors should be used to obtain images with high spatial resolution.
