Claim:
1. Method for assessing a regurgitant flow through a valve into a moving object of interest from a sequence of consecutive two-dimensional (2D) X-ray images of such moving object of interest, which 2D X-ray images are timely separated by a certain time interval, the method comprising: a) identifying in the 2D X-ray images the moving object of interest; b) augmenting the 2D X-ray images to stabilize position of the moving object of interest in the 2D X-ray images in order to correct for motion of the moving object of interest in the 2D X-ray images, wherein the motion is selected from the group consisting of cardiac motion, breathing motion, patient motion and combinations thereof; c) making a time-analysis of the augmented 2D X-ray images of b) to obtain at least one time-density curve, wherein the at least one time-density curve represents a time-evolution of pixel brightness; d) determining a plurality of parameters related to such at least one time-density curve; and e) weighting such parameters to provide indications on the regurgitant flow through the valve.
