Imaging observation timing for assisting radiation treatment

A system comprising:

• an imaging element configured to generate a first observation of an object, the first observation generated at a first time (t1), the object associated with a volume of interest (VOI), the VOI comprising a volume within a body of a patient;
• one or more processors configured to:
• determine a first positioning of the VOI based at least in part on the first observation of the object;
• adaptively determine a second time (t2) for the imaging element based at least in part on a positioning parameter associated with the first positioning of the VOI, wherein the positioning parameter includes at least one of a velocity or an acceleration of the VOI, and wherein the adaptively determined second time (t2) is dependent on the at least one of the velocity or the acceleration of the VOI exceeding a threshold;
• and
• generate a second observation, using the imaging element, of the object at the second time (t2).
