METHOD AND DEVICE FOR ANALYSING REGION OF INTEREST IN OBJECT USING X-RAYS Russian patent published in 2016 - IPC G01N23/04 

FIELD: physics.

SUBSTANCE: invention can be used to analyse a region of interest in an object using X-rays. The invention comprises (a) providing measurement data by using a differential phase contrast X-ray imaging system, and (b) analysing characteristics of the object in the region of interest. The measurement data comprise a two-dimensional or three-dimensional set of pixels, wherein for each pixel the measurement data comprise three types of image data spatially aligned with each other, including (i) absorption representing image data A, (ii) differential phase contrast representing image data D, and (iii) coherence representing image data C. The analysis step is based, for each pixel, on a combination of at least two of information comprised in the absorption representing image data A and information comprised in the differential phase contrast representing image data D and information comprised in the coherence representing image data C.

EFFECT: high reliability of segmentation or classification of internal structures in an object of interest.
