1. A computer-implemented method of performing a treatment fraction of radiation therapy, the method comprising:
determining a current position of a target volume of patient anatomy;
based on the current position of the target volume, computing an accumulated dose for tissue disposed within the target volume;
determining that the accumulated dose is less than a current dose budget of the tissue; and
in response to the accumulated dose being less than the current dose budget, applying a treatment beam to the target volume while the target volume is in the current position.
