METHOD FOR MULTI-FRAME RECORDING OF RADIOGRAPHIC IMAGES (VERSIONS) Russian patent published in 2020 - IPC G01N23/04 

FIELD: physics.

SUBSTANCE: invention can be used for multi-frame digital surveying when investigating fast processes. Essence of the invention is that ionizing radiation (IR) is passed through the analyzed object, selecting time intervals to obtain radiographic images (RI) frames, for each selected time interval detecting the storage luminescent screens (SLS) in number of at least one, arranged one after another along the IR path, passing the IR through the SLS, in the sensitive layer of each of the SLS simultaneously forming a latent image of the analyzed object, cleaning them from the formed latent image, irradiating it with pulses of electromagnetic radiation, then, after formation of latent image at all SLS, they are read, and frames RI are obtained by mathematical processing based on difference of images read by SLS.

EFFECT: enabling multi-frame recording of a radiographic image in ionizing radiation with high spatial (tens of mcm) and temporal (<1 mcs) resolutions, as well as low level of distortion.
