Abstract

This study assessed an instructional video for patient education on respiratory gating in breast cancer radiotherapy. Among 476 patients, the video-based workflow increased lung volumes and the proportion undergoing respiratory gating, while maintaining high target coverage and low doses to organs of interest, supporting the feasibility of using video instruction to achieve effective gating.
