ABSTRACT:
A device (1) for computer tomography, which is set up for x-ray scatter correction, features an evaluation unit (17) which evaluates values stored as a table in a data memory for x-ray scatter correction, which have been determined in advance with the aid of a Monte Carlo simulation which take account of interactions of the photons with the object (2) to be investigated.
