Abstract
A method includes determining a first set of positions for a volumetric imager and determining a second set of positions for a linear accelerator (LINAC), during radiation treatment delivery. The method further includes determining a set of radiation beam directionalities of the LINAC, wherein for each of the second set of positions for the LINAC a radiation beam corresponds to a radiation beam directionality. The method further includes generating instructions for the volumetric imager based on the first and the second set of positions, the radiation beam directionalities, and a treatment time constraint to avoid a collision between the volumetric imager and the LINAC and between the volumetric imager and the radiation beam, wherein the instructions include physical locations of the volumetric imager and timing values corresponding to the physical locations. The method further includes operating the volumetric imager during the radiation treatment delivery according to the set of instructions.
