摘要:
The proposed technical solution refers to the field of medical technology, more precisely to X-ray fluorographs, used for screening of diseases of the chest cavity.The purpose of this work is to equip the digital X-ray camera with the alignment elements of the comparator.The technical result of the utility model is expressed in the expansion of the technical means of machine X-ray diagnostics. It is achieved by the fact that in a digital X-ray fluorography chamber containing a light-proof housing protected by lead with an entrance window covered with a protective screen of radiopaque and opaque material to which a flat-shaped fluorescent screen adjacent to the interior of the chamber is optically coupled by a high-speed lens with a digital type connected to an electrical signal processing unit including a signal amplifier, an analog-to-digital converter, a phono circuit a digital image matrix, connected via a playback circuit to a video monitor, as well as an electric signal processing unit with a digital archive of test images, and a comparator, which has two inputs, one of which is connected via a switch to the archive of test pictures, and the other to the digital matrix of the current image, and the output of the comparator is connected to the analyzer of the resulting signal, equipped with the "Normal pathology" indicator, the electric signal processing unit is connected to the panel control, on the outer surface of the protective screen, at its angles, at a distance of 20-25 mm from the nearest boundaries of the working field of irradiation fixed coordinate marks made of radiopaque material are fixed, and the block of images The electric signal is supplemented by the electrical scaling of the test image and the scheme for moving the test image relative to the current image in two mutually perpendicular directions. and the other to the digital matrix of the current image, and the output of the comparator is connected to the analyzer of the resulting signal, equ
