1. A method to generate image data representing a moving object inside of an examination subject, comprising: operating an image data acquisition device to acquire raw data, at respectively different acquisition points in time, from a region of an examination subject comprising a moving object; providing said raw data to a computerized processor and, in said processor, automatically generating position overview data respectively for the different acquisition points in time from at least a portion of said raw data; in said processor, automatically determining a scattering of at least a portion of the position overview data, said scattering being dependent on the respective acquisition point in time; in said processor, automatically selecting spatial test regions within said position overview data, dependent on the determined scattering; in said processor, automatically determining, for each of the selected spatial test regions, a trust parameter value; and in said processor, reconstructing image data from at least some of said raw data, dependent on the respective trust parameter values of the respective different spatial test regions.
