Assessment of the Effectiveness of a Visual Coaching Device Combined with Auditory Instructions on Reproducibility and Stability in Deep Inspiration Breath-Hold Radiotherapy.

ABSTRACT: Background/Objectives: In left-sided breast cancer radiotherapy, deep inspiration breath-hold (DIBH) reduces radiation dose to the heart; however, its success depends on the patient's ability to maintain reproducible and stable breath-holds. Although visual and auditory guidance systems have been introduced to improve performance, quantitative data on their combined effects remain limited. Methods: We retrospectively analyzed 400 breath-hold sessions in 20 patients undergoing DIBH treatment using synchronized visual and auditory coaching. Real-time respiratory displacement data were used to calculate reproducibility and stability. Temporal trends and correlations between reproducibility and stability were also assessed. Results: The mean reproducibility was 0.51 ± 0.22
