Abstract

A method and a measurement system are disclosed for the noninvasive determination of properties of an object to be examined and to the use of a contrast medium for X-ray phase-contrast measurement. in at least one embodiment of the invention, a mixture (suspension) consisting of a base liquid and a multiplicity of particles contained therein is used, the refractive index of the base liquid being different to the refractive index of the particles.
