Method for scattered radiation correction in the case of an X-ray CT, and X-ray CT for applying this method

An X-ray CT comprising:

• at least one bifocal detector system;
• and
• a control and arithmetic unit to produce tomographic pictures, the control and arithmetic unit containing program code that, upon being executed, carries out the following,
• determining a potential scattering site for each measuring beam from radiation tangents, determinable in a sinogram, to a scanned object, and
• calculating an intensity of scattered radiation from a scattering beam striking the determined scattering site, and angle ratios of the scattering beam, the radiation tangent to the examination object and the measuring beam.

An X-ray computer tomograph, comprising:

• at least two X-ray sources, wherein scattered radiation from the at least two X-ray sources is determined on the basis of a sinogram currently being measured from a scanned object;
• means for determining a potential scattering site for each measuring beam from radiation tangents, determinable in a sinogram, to the scanned object;
• and
• means for calculating an intensity of the scattered radiation from a scattering beam striking the determined scattering site, and angle ratios of the scattering beam, the radiation tangent to the examination object and the measuring beam.
