Abstract
A method and system for physiological gating for radiation therapy is disclosed. A method and system for detecting and predictably estimating regular cycles of physiological activity or movements is disclosed. Another disclosed aspect of the invention is directed to predictive actuation of gating system components. Yet another disclosed aspect of the invention is directed to physiological gating of radiation treatment based upon the phase of the physiological activity.

26. A method of generating a signal, comprising:
-
determining a variable representative of a degree of completion of a cycle of a physiological movement; and
generating a signal based upon the variable;
wherein the variable is determined using a first set of data obtained at a first time and a second set of data obtained at a second time. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
