Abstract (en)
[origin: WO2022232749A1] Systems and methods are disclosed for monitoring anatomic position of a human subject for a radiotherapy treatment session, and optionally modifying a radiotherapy treatment based on anatomic position changes. Example operations for movement monitoring and therapy control include: obtaining 3D image data for a subject, which provides a reference volume and at least one defined region of interest; obtaining real-time 2D image data corresponding to the subject, captured during the radiotherapy treatment session; extracting features from the 2D image data; producing a relative motion estimation of a region of interest with a machine learning regression model, the model trained to estimate a spatial transformation from the 2D image data based on training from the reference volume; and controlling a radiotherapy beam of a. radiotherapy machine used in the radiotherapy session, based on the relative motion estimation.
