Abstract

A method is disclosed for acquiring measured data by way of a computed tomography system, wherein the measured data is acquired by a detector unit disposed opposite the radiation source during a rotation of a radiation source around an examination object. In at least one embodiment, the rotation is subdivided into succeeding time segments during each of which measured data is acquired, and each of the succeeding time segments has either a first length or a second length consisting of two predefined lengths.
