Claim 4:
5. The method of claim 3, wherein correcting the motion cycles of the motion signals based on the durations of actual motion cycles comprises:
for each peak of the plurality of peaks of the respiratory signal, determining a first duration between the peak and a corresponding valley, a second duration between the peak and a next peak, and a third duration between the peak and a valley next to the corresponding valley;
determining a probability that each of the first duration, the second duration, and the third duration corresponds to an actual respiratory cycle based on at least one of the first distribution of the respiratory cycles or the second distribution of the half respiratory cycles;
determining the first duration, the second duration, or the third duration that has a maximum probability as the duration corresponding to the actual respiratory cycle; and
correcting the respiratory cycles of the respiratory signal based on the duration corresponding to the actual respiratory cycle.
