1. A method for imaging an object subject to a cyclic motion, wherein a predefined total number of two or more consecutive imaging repetitions is carried out by using an imaging modality, wherein a duration of each imaging repetition is given by a predefined repetition time, wherein each of the two or more imaging repetitions comprises a sequence of equally spaced imaging events, wherein each imaging event has an event number, which corresponds to a respective predefined imaging parameter, the method comprising:
determining a cycle duration of the cyclic motion;
determining a maximum number of events per cycle based on the cycle duration, the repetition time, and a predefined event spacing time;
determining a shift number at least in part randomly;
determining, for a first imaging repetition of the two or more imaging repetitions, a starting number depending on the maximum number of events per cycle and the shift number; and
carrying out the first imaging repetition, wherein the respective sequence is started with an imaging event, whose event number is given by the starting number.
