Abstract

Systems and methods for tracking cardiac targets are disclosed. The cardiac targets may be tracked dynamically. The process may include registering a cardiac target at different phases of a cardiac cycle. Movement of the cardiac target can be determined by correlating respiratory motion and cardiac pumping motion. Radiation treatment can then be delivered to the cardiac target taking into account the movement of the cardiac target.
