ABSTRACT:
Methods and systems are disclosed for radiation treatment of a subject involving one or more fractional treatments. A fractional treatment comprises: obtaining fractional image data pertaining to a region of interest of the subject; performing a fractional optimization of a radiation treatment plan to determine optimized values of one or more radiation delivery variables based at least in part on the fractional image data; and delivering a fraction of the radiation treatment plan to the region of interest using the optimized values of the one or more radiation delivery variables as one or more corresponding parameters of the radiation treatment plan. A portion of performing the fractional optimization overlaps temporally with a portion of at least one of: obtaining the fractional image data and delivering the fraction of the radiation treatment plan.
