Claim Text:
1. A method, comprising: obtaining a signal that includes a plurality of cycles; generating a map that maps motion phases to the signal based on both an amplitude and a slope of the signal, wherein the map divides each cycle into a descending region and an ascending region, and the descending region includes a portion of the signal with a negative slope between a lesser of a cycle maximum and a mean of signal maxima of the plurality of cycles and a greater of a cycle minimum and a mean of signal minima of the plurality of cycles, and the ascending region includes a second portion of the signal with a positive slope between the lesser of the cycle maximum and the mean of the signal maxima and the greater of the cycle minimum and the mean of the signal minima; and generating volumetric image data based on data acquired by a scanner and the mapped motions phases.
