This study quantifies absorbed organ doses in head-and-neck IGRT, emphasizing the benefit of optimized anatomy-specific protocols. Using OSLDs in an anthropomorphic phantom, we measured doses for two dedicated head-and-neck protocols (Standard S10\/CBCT2 and Low-dose S20\/CBCT3). Additionally, a non-optimized chest protocol (CBCT1) was evaluated to quantify the dosimetric penalty of potential protocol misapplication. The misapplied chest protocol resulted in severe overexposure (spinal cord dose $\\approx $ 81 mGy per scan). In contrast, the optimized head-and-neck protocols maintained organ doses below 20 mGy per scan. Comparing the optimized protocols, the Standard S10 provided a balanced dose profile, while the Low-dose S20 reduced exposure but showed higher variability near bone interfaces. Results show that strict adherence to anatomy-specific protocols is a critical radiation protection imperative to avoid unnecessary exposure.<\/jats:p>","DOI":"10.1093\/rpd\/ncag077","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T09:54:29Z","timestamp":1784627669000},"page":"1393-1400","source":"Crossref","is-referenced-by-count":0,"title":["Impact of kV-CBCT protocol selection on organ dose in head-and-neck IGRT: an OSLD phantom study"],"prefix":"10.1093","volume":"202","author":[{"given":"Yassine","family":"Aguezzoumen","sequence":"first","affiliation":[{"name":"Faculty of Sciences, Ibn Zohr University , LPMC Lab., P.O.
