AbstraktAbstract
The invention deals with a radiation imaging method including steps of generation of at least one radiation microbeam by a radiation source, radiation penetration through the examined object and its caption by a detector consisting of a system of pixels, while the difference between the position of a non-refracted microbeam detected without the examined object and the position of a refracted microbeam detected with the examined object defines refraction angle in a particular point of the examined object expressing the size of local gradient of refractive index corresponding to the phase gradient image (PGI) of the examined object.
