METHOD OF OBTAINING AND PROCESSING IMAGES FORMED USING PROTON RADIATION Russian patent published in 2020 - IPC G01N23/04 G06T5/00 

FIELD: proton radiography.

SUBSTANCE: invention relates to proton radiography, particularly to methods of processing images formed with the help of proton radiation, and can be used, for example, in digital photography systems to determine the internal structure of objects or to study fast processes. Method involves obtaining digital images of a proton beam using at least two recording systems, the first of which is placed to the field of study, and the second – after, to obtain at least one image to the field of study and at least two images from different views after the field of study by passing a proton beam through the magnetooptical system, an auxiliary object placed before the first recording system, and the study area, processing the obtained images of the auxiliary object by selecting projective transformations, translating images obtained from the first recording system, to the image view from other recording systems, then, performing pixel-by-pixel division of last images on the resulted images from the first registration system, obtaining images of the field of research from different angles, reducing them to one aspect angle. Thereafter, the accuracy of bringing the images to the same angle is evaluated by using the test object in the form of two plates orthogonal to each other, which is placed in the study region, obtaining its image, at that, by turning and changing the plates inclination, their minimum thicknesses on the images are achieved, which indicates orientation of the plate plane strictly along the proton beam, then previously selected additional projective transformations are used to reduce plate images to one view, then, processing said images, constructing intensity profiles of the proton beam perpendicular to the image of plates with subsequent approximation thereof by Gauss function, such a procedure is repeated for images from all cameras of recording systems installed after the object of analysis, and when comparing coordinates of centers of all obtained intensity profiles, average or mean square error of reducing images to one angle is calculated to determine degree of reliability of comparison and analysis.

EFFECT: high accuracy of processing recorded proton images.
