1. A computer-implemented method of performing radiation therapy on a target volume within an anatomical region of a patient, the method comprising:
acquiring a cone-beam computed tomography (CBCT) image of the anatomical region while the anatomical region is positioned in a first preliminary treatment location;
reconstructing a current digital volume of the anatomical region based on the CBCT image of the anatomical region;
generating a first beam's-eye-view of the anatomical region based on the current digital volume and an offset between the first preliminary treatment location and a reference treatment location;
modifying the first beam's-eye-view of the anatomical region with one or more visual cues associated with a treatment field for the target volume; and
displaying the first beam's-eye-view with the one or more visual cues.
