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.
Direct-to-unit (DTU) adaptive radiation therapy (ART) is an emerging workflow that reduces treatment delays for urgent radiation therapy by eliminating the need for a separate simulation scan. Despite increasing clinical adoption, standardized commissioning g...
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...
This study evaluates whether selective distance-based cropping of organs at risk (OARs) can improve target coverage and plan robustness for abdominal stereotactic adaptive radiation therapy using the Ethos 2.0 planning system. By reducing OAR volume and thus...
