Claim 6:
7. The method of claim 6, wherein the determining the cardiac motion parameter corresponding to the each cardiac motion phase based on the one or more vascular images of interest includes:
determining a first vascular center in each vascular image of interest of the each cardiac motion phase;
determining a displacement of the first vascular center based on a first position of the first vascular center in the each vascular image of interest and a second position of a second vascular center in a vascular image of interest of another cardiac motion phase adjacent to the each cardiac motion phase;
determining an interval between the each cardiac motion phase and the another cardiac motion phase adjacent to the each cardiac motion phase; and
determining, based on the displacement and the interval, a motion rate of the first vascular center; and
designating the motion rate of the first vascular center as the cardiac motion parameter.
