Zusammenfassung:This study aimed to develop and validate a comprehensive, reproducible and automatic 4DCT Quality Assurance(QA) workflow (QAMotion) that evaluates image accuracy across various regular and irregular breathing patterns. Volume and amplitude deviations, CT number accuracy, and spatial integrity were used as evaluation metrics. For repeatability tests, tolerances were respected with a mean CT number deviation
