Method for assessing motion and/or deformation of a moving tissue or object from a sequence of at least two consecutive image frames of such tissue or object, which images are timely separated by a certain time interval, the method comprising the following steps:- defining a certain number of reference points at least on one image frame of the sequence of image frames- determining the velocity of motion of such reference points between two successive image frameswherein- the at least one image frame is rescaled to fit within a reference window- a reference image is superimposed on such rescaled image frame- the reference points are defined by matching points on the rescaled image frame to corresponding points on the reference image.Also a corresponding apparatus is disclosed.
