1. A method for producing CT images of a partially cyclically moving examination object, comprising: scanning the examination object in one pass by a spiral movement of at least one focus and at least one detector oppositely situated; performing the scanning of the examination region at a relative feed rate between gantry and couch; determining a three-dimensional image of absorption coefficients with the aid of a multiplicity of sectional planes of an examination volume on the basis of the data obtained by scanning; determining at least one static object area and at least one at least partially moving object area with reference to the examination object with the aid of cyclical intrinsic movement; and using, during a pass when scanning the examination object, a first feed rate in the at least one moving object area, and using another, second feed rate in the at least one static object area.
