FIELD: physics.
SUBSTANCE: invention relates to X-ray equipment and can be used in designing digital X-ray diagnostic devices for medical and industrial purposes. Disclosed digital X-ray receiver comprises a light-proof housing, an X-ray screen, a mirror, a photosensitive camera with a high-aperture lens and a mechanical system which enables to adjust the spatial position of the photosensitive camera relative to the X-ray screen while maintaining the sharpness of the projected image. Mechanical system comprises two linear guides with carriages and reversible electric drive connected with carriages. Note here that photosensitive camera is installed on one carriage, while second carriage and focusing ring of lens are interconnected by tie rod with cylindrical hinges at its ends. Linear guides are installed relative to each other at an angle of ϕ=arctg(b/c×2×tgα/2), where α is the angle of rotation of the focusing ring of the lens; c is the camera displacement path; b is the shortest distance from the center of the focusing ring of the lens to the thrust.
EFFECT: high information value of reproduced images and reduced dose load on the diagnostic object.
