13. An apparatus, comprising:
-
a treatment planning system coupled to a diagnostic imaging system and a treatment delivery system; and
a digital processing device coupled to the treatment planning system, the digital processing device configured to generate a plurality of correlation models descriptive of an internal path of movement of a target and to select one of the plurality of models to derive a target position of the target. - View Dependent Claims (14, 15, 16, 17, 18)

19. An apparatus, comprising:
-
means for generating a plurality of models, each of the plurality of models descriptive of an path of movement over time of a target;
means for determining which one of the plurality of models most closely approximates an actual position of the target at a specified displacement point; and
means for tracking the target using the one of the plurality of models that most closely approximates the actual position of the target. - View Dependent Claims (20, 21)
