61 Fluorescent plate-storage media are made in standard formats of an X-ray film, placed in the cassette instead of the usual ‗film-intensifying screen‘ kits and used in conventional X-ray devices. Fluorescent plate- storage media have larger exposure range if compared to the conventional film- screen combinations greatly extending the under-exposure and overexposure interval. Thus, it is possible to receive quite contrasting images even with the lower exposure dose, where the level of quantum noise is the only lower limit. In such a case, the image capability is up to 8 bits/pixel. The spatial resolution of a fluorescent digital X-ray radiography is determined by the size of the pixel ranging from 0.1x1.0 mm while using storage screens not more than 20x20 cm and up to 0.2x0.2 mm while using screens with the size of 35x43 cm. In addition, there are publications about creating a matrix with a 0.1 mm pixel. Such spatial resolution of such matrices ranges from 2.5 pairs of lines/mm (with a 0.2 mm pixel) to 5-6 pairs of lines/mm (with a 0.1 mm pixel). These specifications of spatial resolution are similar to the modern systems of traditional X-ray radiography [9, 10]. Digiskan 2T Plus (Siemens) would be an example of the modern X-ray diagnostic device based on a photostimulated luminescence. It is worth noting that this technology can be used with the current park of X- ray devices. Digital X-ray radiography on the basis of the multi-chamber technology. X-ray images receivers on the basis of multi-chamber technology is a home-grown technology. The working principle of these devices is to read an X-ray image from the luminescent screen by CCD-matrices digital cameras. The use of several cameras (4 to 36) makes it possible to increase the spatial resolution. Each camera images received after processing are ‗seamed‘ and form a diagnostic image being displayed on the screen of the workstation. The spatial resolution of these devices is 2.4 - 4 pairs of lines per mm, and the graduation resolution of 1024 shades of gray (10 bits per pixel). The systems of digital scanning of X-ray images for aposterior processing - such systems are the devices for digital input of images from a film into a computer being the flatbed scanners equipped with a slide module or special digitizers. The advantage of digital X-ray radiography if compared to the conventional screen-film X-ray radiography is greater visibility of minor contrast differences and essentially higher exposure latitude, meaning high-quality images significantly reducing the radiation-absorbed dose for patients and medical personnel. A posteriori image processing (post processing) makes it possible to improve its quality. The digital image can be easily and handily analyzed by special image processing workstations [11]. Thanks to the various programs it is possible to calculate the linear sizes, the area and the volume of any mass, both automatically and upon the special request of the physician. It is possible to determine the angles between different anatomic lines. It is possible to outline the parts of the image, increase and decrease the contrast, chose any objects, smoothly change their scale, and build three-dimensional images, etc both automatically and manually. If we are talking about the gradation resolution, it is known that a common person eye is able to distinguish up to sixteen grades of gray, and the eye of a specially trained person is able to distinguish up to thirty grades of gray. Thus, to diagnose a target, the physician, while considering the image, is able to use only two or three dozen of gray-tone gradations resented by a photocarrier. To find the objects contained in more subtle shades of gray it is necessary to use other parameters of radiation exposure. Today, while registering an image, the digital methods provide a dynamic range of halftones ten times greater than the perception of a human. Thanks to the computer programs moving interval of 16 to 32 degrees, that is seen by the naked eye, throughout this range, the physician is able to find previously invisible parts without repeated examination of the patient by sequentially modifying the image on the computer screen. The use of color coding makes it possible to use the whole dynamic range, replacing the tone contrast with the color one. Adjoining parts, whose optical density is almost the same, are assigned contrasting colors thus making the area distinguishing more reliable. Moreover, all image areas having the same optical density should receive the same color. Conclusions . It is possible to store digital images without any data loss and transfer them for analysis to other workstations. The systems of digital X-ray radiography may be combined with the systems of electronic archiving and image transfer. These networks make it possible to simultaneously transmit copies of images being completely identical to the original to different points. The transition to telegraphy and telemedicine is possible thanks to the creation of the electronic system of images processing and transfer and the possibility of comparing the results of various diagnostic studies (PACS). The digital images archive significantly reduces the need for areas and eliminates the risk of images loss. Conventional X-ray images tend to deteriorate due to natural a process, that is why when archiving a magnetic film or microfilm it is
