Adaptive radiotherapy (ART) requires accurate daily volumetric imaging, yet cone-beam CT (CBCT) is fundamentally limited by X-ray scatter, leading to degraded contrast, CT number inaccuracy, and reduced reliability of automated segmentation. These limitations...

To compare different dual-energy cone-beam CT (DE-CBCT) configurations for the Varian HyperSight system via relative electron density (ED) and effective atomic number (EAN) quantification, as well as contrast improvement.
