Abstract

A computer-implemented method, a system or a non-transitory computer-readable medium of doing the same, for monitoring movement of anatomical features throughout a radiation treatment session. The method may include monitoring the movement of the anatomical features with a first modality. The method may further include obtaining positional information of the anatomical features with a second modality over a finite acquisition time. The method may also include providing an indication of a clinically relevant movement associated with the anatomical features during the finite acquisition time based on the monitored movement from the first modality.
