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.
Claims27
A method of gating an application of radiation, comprising:
- obtaining a first set of data representative of a physiological movement of a patient during a first time period;
- obtaining a second set of data related to a measured physiological movement of the patient during a second time period;
- comparing the first set of data with a second set of data;
- and
- gating an application of radiation to the patient based on a result of the comparing.
2 more elements
A method for gating an execution of a procedure, comprising:
- determining a variable representative of a degree of completion of a cycle of a physiological movement;
- and
- gating an execution of a procedure based upon the variable.
