Introduction: MR-guided adapted radiotherapy (MRgART) using a high field MR-linac has recently become available. We report the estimated delivered fractional dose of the first five prostate cancer patients treated at our centre using MRgART and compa

Purpose This study aimed to quantify the coverage probability for esophageal cancer radiotherapy as a function of a preset margin for online MR-guided and (CB)CT-guided radiotherapy. Methods Thirty esophageal cancer patients underwent six T2-weighted

Highlights • The patterns of practice for adaptive radiotherapy were evaluated for 177 centres. • Over half performed ad-hoc adaption but less than a third used specific protocols. • CBCT was the main imaging modality in general but MR was used

Background and purpose Detailed knowledge of target motion is important for improved accuracy and decreased toxicity of esophageal cancer radiotherapy. This study uses the 3D trajectories of implanted markers during setup CBCT scans to investigate th
