Abstract
Disclosed are computer-implemented methods, systems, and computer program products for displaying superimposed image contours. A first centroid or center-of-mass of a contour extracted from a first image that depicts a moving object as the object appeared at a first time is calculated. A second centroid or center-of-mass of a second contour extracted from a second image that depicts the object as the object appeared at a second time is also calculated. The second image depicts the object in substantially the same plane as the first image. The first and second contours are displayed with the respective first and second centroids or centers-of-mass positioned at a common location. In some implementations, the images are ultrasound images depicting, for example, a human heart. The images can be transgastric short axis views of the human heart.
