To evaluate the impact of patient size on cone-beam CT (CBCT) image quality using iterative reconstruction approaches on the Varian Ethos HyperSight imaging system and to assess the adequacy of attenuation and scatter correction across patient sizes.

The purpose of this study was to characterize the dosimetric consequences of direct CBCT dose calculation for abdominal stereotactic adaptive radiotherapy by comparing dose distributions calculated on simulation CT (simCT) versus HyperSight CBCT (HsCBCT). Emp...
