Claim One:
1. A method of motion artifact compensation in a projection data set of an object of interest, wherein the projection data set is acquired by means of a source of electromagnetic radiation generating a beam and by means of a radiation detector detecting the beam, the method comprising the steps of: compensating the projection data set for a motion artifact on the basis of the difference, resulting in a motion artifact compensated projection data set; reconstructing the object of interest from the motion artifact compensated projection data set, resulting in a motion artifact compensated image; wherein a first ray and a second ray create projection data of the projection data set; wherein the first ray and the second ray are opposite rays passing through a single object point; determining a difference of the projection data of the first ray and the projection data of the second ray; and wherein the difference of the projection data of the first ray and the projection data of the second ray is due to the motion of the object of interest resulting in motion artifacts.
