Abstract:
1. A method comprising: identifying a first landmark point in a first cardiac image; identifying a first centroid of a left ventricle depicted in the first cardiac image; performing a first Cartesian-to-polar transformation to form a first rectangular representation of the left ventricle depicted in the first cardiac image based on the first landmark point and the first centroid; identifying a second centroid of the left ventricle depicted in a second cardiac image; computing a second landmark point in the second cardiac image based on the second centroid, the first centroid and the first landmark point; and performing a second Cartesian-to-polar transformation to form a second rectangular representation of the left ventricle depicted in the second cardiac image based on the computed second landmark point and the second centroid, wherein the first and second cardiac images depict different portions of the left ventricle.
