METHOD FOR X-RAY TOMOGRAPHY AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2014 - IPC G01N23/04 

FIELD: physics.

SUBSTANCE: method involves irradiating and picking up an array of images of the energy spectrum of X-ray radiation passing through the object, wherein the images are reconstructed from shadow projections of the object; generating, comparing and analysing current and reference integral characteristics of the image of the object; determining defects of the object and displaying object analysis results; the method being characterised by that reconstruction of the three-dimensional image is carried out by rotating and shifting the object on three mutually perpendicular axes of a coordinate system associated with the working area of the object while adjusting control of the latter, and current and reference integral characteristics of the image of the object are generated in form of spectral and fractal features.

EFFECT: high accuracy of assessing the inner structure of an object, high-speed of operation, broader functional capabilities and reduced hazard for maintenance personnel due to considerable X-ray exposure.
