X-ray CT method, sample holder and X-ray CT apparatus

摘要

The invention relates to an X-ray CT method and in particular to registration-based dark field tensor tomography method for examining a sample (60) by means of X-radiation, in which a sample (60) is scanned successively with at least two mutually different fixed orientations of one under rotation about a respective fixed axis of rotation by means of X-radiation in that each time the sample (60) is oriented on the basis of dark-field signals, a plurality of scatter records are detected and the scatter records matched to different orientations by registration and a common scatter record reflecting an optional angular dependence of the scattering by the sample (60) to be united.
