Detection scheme for x-ray small angle scattering

A method for x-ray small angle scattering, the method comprising:

• emitting, by an x-ray source, an x-ray beam, the x-ray beam comprising a plurality of photons;
• detecting, by a detector, one or more small angle scattered photons, the scattering related to an object to be imaged;
• passing, by an x-ray small angle scattering apparatus, one or more small angle scattered photons;
• and
• blocking, by the x-ray small angle scattering apparatus, one or more Compton scattered photons and one or more main x-ray photons,
• the x-ray small angle scattering apparatus comprising:
• a first grating comprising a plurality of first grating cells, and
• a complementarity second grating comprising a plurality of second grating cells, the second grating positioned relative to the first grating,
• a configuration of the first grating, a configuration of the second grating and the relative positioning of the gratings configured to pass one or more small angle scattered photons and to block one or more Compton scattered photons and one or more main x-ray photons.
