“…This limitation can be also be overcome by the new HyperSight ™ CBCT technology which has novel features such as extended FoV up to 70 cm, as well as an advanced reconstruction techniques for improved image quality [33,35,36]. Also, it captures images in less than 6 s, which is 10 times faster than a conventional linear-accelerator-based imaging system (Fig.…”

“…Also, it captures images in less than 6 s, which is 10 times faster than a conventional linear-accelerator-based imaging system (Fig. 1) [35,37,38]. This allows tumors that move with respiration to comfortably perform a single breath-hold for the machine to obtain high-quality images needed for daily treatment planning and delivery.…”

Adaptive radiotherapy (ART) was introduced in the late 1990s to improve the accuracy and efficiency of therapy and minimize radiation-induced toxicities. ART combines multiple tools for imaging, assessing the need for adaptation, treatment planning, quality assurance, and has been utilized to monitor inter- or intra-fraction anatomical variations of the target and organs-at-risk (OARs). Ethos™ (Varian Medical Systems, Palo Alto, CA), a cone beam computed tomography (CBCT) based radiotherapy treatment system that uses artificial intelligence (AI) and machine learning to perform ART, was introduced in 2020. Since then, numerous studies have been done to examine the potential benefits of Ethos™ CBCT-guided ART compared to non-adaptive radiotherapy. This review will explore the current trends of Ethos™, including improved CBCT image quality, a feasible clinical workflow, daily automated contouring and treatment planning, and motion management. Nevertheless, evidence of clinical improvements with the use of Ethos™ are limited and is currently under investigation via clinical trials.
