Imaging observation timing based on radiation treatment system element delay

摘要

Systems, methods, and apparatuses are provided for configuring a radiation treatment system based on a plurality of volume of interest (VOI) positioning. One system includes an imaging element configured to generate a first observation of an object, the first observation being generated at a first time, wherein the object is associated with a volume of interest (VOI), and the VOI includes a volume within a body of a patient. The system further includes determining a first positioning of the VOI based at least in part on the first observation of the object, determining a second time for the imaging element based at least in part on a positioning parameter associated with the first positioning, and a time offset, and generating a second observation of the object at the second time.

1. A system comprising:
an imaging element configured to generate a first observation of an object, the first observation generated at a first time (t1) during a radiation delivery, 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) during the radiation delivery for the imaging element based at least in part on a positioning parameter associated with the first positioning, and a time offset, wherein the time offset is determined based upon a positioning change delay of the system, and 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;generate a second observation of the object at the second time (t2) during the radiation delivery;wherein the system comprises a radiation treatment system, and the radiation treatment system further comprises: a radiation treatment system element configured to aid in administering radiation to at least a portion of the patient based on one or more of the first observation and the second observation, wherein the radiation treatment system element comprises at least one of a beam element, a beam control element, a beam assembly element, an imaging element, a patient couch element.
