Adaptive radiotherapy performed on the daily magnetic resonance imaging (MRI) is an
option to improve the treatment quality. In the adapt-to-shape workflow of 1.5-T MR-Linac …

Purpose MR‐Linac integrates an MRI scanner and a linear accelerator to provide adaptive
radiation treatment. Superior tissue contrast and real‐time imaging can give the clinicians …

Background and purpose The promise of the MR-linac is that one can visualize all
anatomical changes during the course of radiotherapy and hence adapt the treatment plan …

Purpose Dose calculation for MR-guided radiotherapy (MRgRT) at the 0.35 T MR-Linac is
currently based on deformation of planning CTs (defCT) acquired for each patient. We …

Purpose MR-guided radiotherapy (MRgRT) relies on the daily assignment of a relative
electron density (RED) map to allow the fraction specific dose calculation. One approach to …

Background Hybrid magnetic resonance (MR)-Linac systems have recently been introduced
into clinical practice. The systems allow online adaption of the treatment plan with the aim of …

Purpose A hybrid magnetic resonance linear accelerator (MRL) can perform magnetic
resonance imaging (MRI) with high soft‐tissue contrast to be used for online adaptive …

Abstract Purpose Magnetic Resonance (MR)‐guided online adaptive radiation therapy
(MRgOART), enabled with MR‐Linac, has potential to revolutionize radiation therapy …

Online adaption of treatment plans on a magnetic resonance (MR)‐Linac enables the daily
creation of new (adapted) treatment plans using current anatomical information of the patient …

Background and purpose Hybrid magnetic resonance linear accelerator (MR-Linac) systems
represent a novel technology for online adaptive radiotherapy. 3D secondary dose …
