1. A method of gating the application of therapeutic radiation comprising:

  • measuring a first set of signal data representative of a physiological movement of a patient during a first time period;

    pattern matching the first set of signal data with a second set of signal data related to measured physiological movement of a patient during a second time period to identify degree of deviation from periodicity of the physiological movement; and

    gating therapeutic radiation to the patient if the degree of deviation from periodicity exceeds a threshold.
