ABSTRACT:
A method is disclosed for scattered radiation detection and/or for scattered radiation correction. In at least one embodiment, each radiation produced is provided with an individual temporal marker/variation of known magnitude, the change in the measured radiation being investigated for these typical temporal variations, and the fraction of the scattered radiation is inferred from the temporal variation found and, if appropriate, a corresponding correction is carried out. Furthermore, a CT system is disclosed, including a computer program that carries out at least one embodiment of the method.
