Evaluating Image Quality of Cone Beam Computed Tomography Using HyperSight® on the Varian TrueBeam.
PURPOSE The study evaluated the image quality of the cone beam computed tomography (CBCT) system on Varian TrueBeam linear accelerators with HyperSight (TB-HS) and compared it with the standard TrueBeam system (TB-S). Particular emphasis was placed on changes relevant to offline adaptive radiotherapy (ART). METHODS I...
