Researchers have developed a novel deep learning method using dual-domain U-Nets with embedded back projection operators to reconstruct motion-resolved 4D CBCT images. This technique aims to improve image-guided radiation therapy for thoracic cancers by reducing scan times and artifacts associated with patient motion. The CNN model takes free-breathing 3D CBCT projections as input and predicts both a static volume and displacement vector fields representing respiratory motion, without requiring explicit respiratory signals or projection binning.
