Zusammenfassung:Disclosed is a method of determining an orthonormalized structure of interest reference image, the orthonormalized structure of interest reference image for applying to a measured image of the structure of interest to correct for the effect of crosstalk from at least one nuisance structure. The method comprises determining a structure of interest reference image based on knowledge of the structure of interest; determining at least one nuisance structure reference image based on knowledge of the at least one nuisance structure; and orthonormalizing the structure of interest reference image to the at least one nuisance reference image to obtain the orthonormalized structure of interest reference image.
