Abstract
Techniques for adjusting radiotherapy treatment for a patient in real time are provided. The techniques include retrieving a reference plan that includes three-dimensional (3D) volume representation of information for the patient and a plurality of radiotherapy beam delivery segments; identifying a first portion of the 3D volume representation of information for a first beam delivery segment of the plurality of radiotherapy beam delivery segments that includes a volumetric portion of a target irradiated by the first beam delivery segment; accessing a deformation model representing patient deformation during a radiotherapy treatment fraction; deforming the first portion of the 3D volume representation of information based on the deformation model; and updating one or more parameters of a radiotherapy treatment device based on the deformed first portion of the 3D volume representation of information.
