A method is provided for reducing noise in a tomogram and/or volume rendering of at least one object. The noise can occur when scattered radiation artifacts are corrected. At least one tomogram that is affected by scattered radiation and at least one preliminary tomogram that has been corrected by a defined correction method are produced from a plurality of projection image datasets that are affected by scattered radiation. The noise emerging when scattered radiation artifacts are corrected may be reduced by selectively smoothening the noise using a filter based on an edge contour of the at least one object, which contour is rendered in the tomogram that is affected by scattered radiation.
