    摘要： PROBLEM TO BE SOLVED: To provide a method and a system for selecting an arbitrary cardiac phase on a physiological non-electrical signal for cardiac gating.
    SOLUTION: For selecting an optimal trigger point in a cardiac cycle, input data including non-electrical cardiac-related data are analyzed to detect candidate features, the candidate features are sorted to select optimal features, and the optimal trigger point is selected. For selecting the arbitrary cardiac phase for cardiac gating, a trigger point identifying the onset of a systole or diastole phase on a signal is identified; a time δt which is before the trigger point and extending from a time t0 to a time t1 is specified, wherein the time t0 is earlier than the time t1; and a time interval T, during which an image is reconstructed and which extends from time t0 to a time t2 is selected, wherein the time t2 is later than time the t0.
