X-ray radiography takes one of the leading places in the modern diagnostic process. In this context, the diagnostics has the following principles: high quality and informative X-ray image and the lowest radiation hazard. The article presents the features of the formation of digital images in X-ray radiography, current systems of digital radiography, digital scanning and aposterior processing systems, and shows the advantages of digital technologies over traditional methods in X-ray radiography. Keywords: x-ray radiology, X-ray radiation, digital radiography, digital technologies, electronic processing systems, digital images. Introduction . Today the formation of the information content of an object on an X-ray film or a fluorescent screen by dots optical density of which reflects the degree of X-ray absorption by an object is the core principle of X-ray radiography and fluoroscopy. X-ray radiography is a reliable and proven method that has been improving for 120 years. As of today, it has the highest spatial resolution. With that, there are a number of technical, economic and ergonomic (labor process-related) grounds causing the need to find other ways to receive an X-ray image. The poor quantum efficiency of an X-ray film requires the use of large exposure doses, resulting in excessive radiation exposure of the patient. Therefore, the simultaneous transmission of both soft and dense tissues in one image is impossible due to the limited dynamic range of an X-ray film. Due to the same reason, it is impossible to choose the optimum exposure. The expenses for the photochemical process and images development equipment keep growing and become crucial for many clinics, increasing the interest in the transmission to cheaper ways of registration of an X-ray image. The difficulty of keeping a film archive is another disadvantage of the screen-film X-ray radiography. Based on the world statistics, up to 20% of X-ray images are lost when kept in archives or it is difficult to receive them on time. Moreover, radiologists cannot abandon the process of film development requiring time expenditures. It is impossible to transfer the image at a distance. The inevitable defects in the course of development of X-ray images cause repeated examinations increasing the radiation load and labor expenses. An analog electron-optical image enhancement is another way of formation of an X-ray image. At that, the image, originally received on the fluorescing screen, passes through the enhancer, increasing its brightness by a thousand times, after that it is fixed by the receiving TV camera with further on-screen display and video tape recorder displaying. The increase of the quantum efficiency and, consequently, the decrease of the dose of radiation is the undeniable advantage of this technology. However, the spatial resolution of such an image is considerably lower if compared to the X-ray radiography [1, 6].
