Hypersight and Ethos In Pediatric Radiotherapy (NCT07528547)
🩺 Plain-English Summary (8th-Grade Level)
This is a single-center, prospective pilot study evaluating the utility of HyperSight CBCT imaging and Ethos adaptive radiation planning in pediatric patients receiving radiation therapy for non-cranial tumors. Twenty patients aged 18 or under will be enrolled. Participants will receive standard-of-care radiation therapy, with the addition of twice-weekly HyperSight CBCT scans. These scans will be used to assess anatomical changes and generate adapted radiation plans using the Ethos platform. Radiation oncologists and radiation therapists will independently evaluate the need for adaptation, and adapted vs. scheduled plans will be compared using dosimetric and anatomical similarity metrics. An optional sub-study will allow anonymized imaging and planning data to be shared with Varian Medical Systems. The study duration will match the patient's treatment course, typically 1-6 weeks, with no additional follow-up beyond standard care.
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (2 items) and avoid the listed exclusions (1 items).
