Abstract: A method for quantitative flow analysis of a fluid flowing in a conduit from a sequence of consecutive image frames of such a conduit, where such image frames are timely separated by a certain time interval, the method comprising: a) selecting a start image frame and an end image frame from the sequence either automatically or upon user input; b) determining a centerline of the conduit in the start image frame; c) determining a centerline of the conduit in the end image frame; d) selecting a common start point on the centerline of the start image frame and on the centerline of the end image frame either automatically or upon user input; e) selecting an end point on the centerline of the start image frame; f) selecting an end point on the centerline of the end image frame; g) calculating centerline distance between the start point and the end point of the start image frame; h) calculating centerline distance between the start point and the end point of the end image frame; and i) calculating a local flow ve

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.
