A method and an apparatus for correlating two image sequences of a periodically moving object with respect to the periodicity is described. A first frame sequence of the object moving with the first periodicity is acquired. Therein the first frame sequence comprises at least one cycle of motion. A second frame sequence of the object moving with the second periodicity is acquired. Therein the second frame sequence comprises at least one cycle of motion. The first and the second frame sequences are synchronized with respect to the respective periodicity such that same phases of motion of the periodically moving object are correlated to be presented simultaneously. The present invention allows to compare sequences representing a periodical motion with a different number of frames in each of the sequences for the same cycle of motion. Thereby, e.g. image sequences of a beating heart acquired before and after a therapy may be presented in a synchronized way and therefore may be easily compared. |
