Objective. Extended treatment session times are an operational limitation in magnetic resonance imaging guided adaptive radiotherapy (MRIgRT). In this study a novel leaf sequencing algorithm called optimal fluence levels (OFL) and an optimization alg

Highlights • Novel dose reconstruction workflow based on log files and online MR imaging. • Intrafractional motion and dose changes were clinically meaningless in most fractions. • Rarely, large shifts caused the delivered dose to deviate from
