Claim 7:
8. The method of claim 1, wherein the plurality of projection data are generated in a plurality of cardiac cycles, and the determining a phase of interest based on the plurality of cardiac motion parameters includes:
determining a mean phase based on the plurality of cardiac motion parameters corresponding to the at least a portion of the plurality of cardiac motion phases;
for each of the plurality of cardiac cycles,
selecting one or more cardiac motion phases in a preset phase range in the each cardiac cycle of the plurality of cardiac cycles, the preset range including the mean phase;
reconstructing one or more cardiac images of the one or more cardiac motion phases based on one or more sub-sets of projection data of the plurality of projection data corresponding to the one or more cardiac motion phases in the each cardiac cycle;
determining the phase of interest in the each cardiac cycle based on the one or more cardiac images of the each cardiac cycle.
