Abstract
Method for assessing a regurgitant flow through a valve into a moving object from a sequence of consecutive image frames of such object, which images are timely separated by a certain time interval, the method comprising the following steps: a) identifying in the images the object of interest; b) augmenting the images to compensate for protocol intensity variation and/or motion and/or background; c) making a time-analysis of augmented images to obtain time-density curve or curves, wherein time-density curves represent a time-evolution of pixel brightness; d) determining a plurality of parameters related to such time-density curve or curves; e) weighting such parameters to provide indications on the regurgitant flow. A corresponding apparatus and computer program are also disclosed.
