FIELD: physics.
SUBSTANCE: invention relates to X-ray equipment, namely to a method for obtaining a digital X-ray image, and can be used to create X-ray diagnostic devices for medical and industrial purposes. Method comprises irradiating an object with a narrow fan-type scanning beam of X-ray radiation, conversion of radiation intensity transmitted through the object using a two-dimensional X-ray screen to successively illuminated narrow fragments of the optical image and recording them with a narrow exposure window of a two-dimensional photosensitive matrix. During registration of the displayed optical image, the exposure window is moved on the photosensitive surface of the matrix in-phase and synchronously with movement of the trace of the fan-shaped X-ray radiation beam along the X-ray screen. Video signals read from the matrix are digitized and transmitted to the operator's automated workstation.
EFFECT: reduced dose on patient, higher contrast sensitivity of apparatus and quality of reproduced X-ray patterns.
