Abstract

A method for determining a movement phase of a periodically moving object in a plurality of sequentially produced images in a series of images of the periodically moving object. The method includes registering different images in the series of images. The method also includes determining a deformation that has occurred between the registered images. The method further includes—determining the phase of the movement of the moving object for at least one of the images in the series of images based upon the determined deformation.
