Based on the materials that make up the detector and the principle of operation, DR amorphous flat-panel (amorphous selenium, amorphous silicon + cesium iodide / amorphous silicon + gadolinium oxide) imaging technology.
Because of physical limitations, experts generally believe that large-area flat-panel imaging DR technology is not competent, and DR equipment in the image quality of amorphous silicon, selenium flat-panel equipment has a certain gap, but the relative price advantage of the two, a line scanning: also known as a one-dimensional line scanning technology, invented by the Institute of Nuclear Physics of the Russian Academy of Sciences, that is, the domestic ZTE Aerospace in the production of DR; there are illuminated by the dose is low, Equipment cost relative to the advantages of cheaper flat-panel technology, but there is also a long imaging time (a few seconds), low spatial resolution (just launched is 1mm / lp) and the fatal flaws of the low efficiency of the use of X-rays; poorer quality of imaging and the patient will receive a lot of unnecessary radiation.
