Method for scattered radiation correction in an X-ray computed tomography system, and method for generating a tomographic display corrected for scattered radiation, and/or an X-ray computed tomography system

A method for scattered radiation correction in an X-ray computed tomography system having at least two tube-detector systems that are rotatable about a system axis of the X-ray computed tomography system to record a data record for reconstructing an examination object, the method comprising:

• assembling the data record from a multiplicity of data projections and a number of first scattered radiation projections;
• recording the data projections during simultaneous operation of the two tube-detector systems, and to record the first scattered radiation projections, respectively deactivating at least one tube of a tube-detector system with regard to emitting X-radiation;
• correcting, in each case, at least one data projection adjacent to a first scattered radiation projection is for scattered radiation with the aid of a scattered radiation component determined from the respective first scattered radiation projection;
• determining, for the remaining data projections, second scattered radiation projections respectively assigned to the latter from the first scattered radiation projections;
• and
• correcting the rest of the data projections for scattered radiation with the aid of a scattered radiation component determined from the respectively assigned second scattered radiation projection.
