Panel (a). Pie chart demonstrating the mean time required for every step of the workflow for prostate cancer patients treated with online-adaptive UHF IGRT on the 1.5 T MR-Linac. The workflow starts with patient setup, followed by the steps listed in the clockwise rotation order. Mean total duration of each treatment session was 38.2 min. (MRI—magnetic resonance imaging, ATS—adapt to shape, ATP—adapt to position). Panel (b). Workflow graphic (OARs—organs at risk, TV—target volume, QA—quality assessment).
