Advances in X-ray imaging technology

X-ray imaging technology shows a great importance in medication, it uses bremsstradiation to produce images of ray density and energy spectrum distribution through different tissues with different X-ray absorption coefficients of specific energy. There are three devices now widely used today, X-ray apparatus, computed tomography (CT) and digital subtraction angiography (DSA). With the development of computer technology, artificial intelligence and material science, imaging technology is undergoing extensive and profound changes. A bunch of brand new imaging technologies has been used in medication and make X-ray technology develop rapidly. This article discussed the history of three X-ray devices and breakthrough points in the future. We also make some prediction and suggestions for the possible development trend of X-ray technology in China.
