Measuring system and method for the non-invasive determination of properties of an examination subject and contrast agent for the X-ray phase contrast measurement

摘要

The invention relates to a method and a measuring system for the non-invasive determination of properties of a subject under investigation and the use of a contrast agent for X-ray phase contrast measurement. The invention is characterized in that a mixture (suspension) consisting of a base liquid and a plurality of particles therein is used, wherein the Brch differs from the refractive index of the particles n SUB P / SUB.
