ABSTRACT:
In a method for correcting for stray radiation in measured intensity values, the measured intensity values are obtained in an X-ray computed tomography scanner by means of a detector matrix that is situated in a tomography measuring field of the computer tomography scanner and has a multiplicity of detector elements arranged next to one another in a number of adjacent detector rows. At least one reference distribution of the stray radiation intensity is determined in the row direction of the detector matrix, and a stray radiation component of each measured value of intensity is determined starting from this at least one reference distribution, and the measured intensity values are corrected as a function of their respective stray radiation component. In this case, the stray radiation component of the measured values of intensity of at least a fraction of the detector rows is determined by using a recursion method on the basis of the reference distribution.
