Zusammenfassung:A phantom material may be irradiated with varying energy x-rays to determine its phase shift properties. A determination of the difference between those phase shift properties and the phase shift properties of another material of interest can be represented and stored in terms of a polynomial function. The stored function can then be used in combination with a surrogate phantom shaped in the form of another object to obtain the phase shift properties of that other object as if it were made from the material of interest.
