Magnetic resonance-guided radiation therapy (MRgRT) not only allows for superior soft-
tissue setup and online MR-guidance during delivery but also for inter-fractional plan re …

Background and purpose Radiotherapy plan verification is generally performed on the
reference plan based on the pre-treatment anatomy. However, the introduction of online …

Magnetic resonance imaging-guided radiation therapy (MRIgRT) has improved soft tissue
contrast over computed tomography (CT) based image-guided RT. Superior visualization of …

The widespread use of volumetric image guidance in external beam radiation therapy can
be traced back to the development of x-ray flat panel technology, which allowed the …

Background and purpose MRI-guided online adaptive treatments can account for
interfractional variations, however intrafraction motion reduces treatment accuracy …

Adaptive radiotherapy (ART) strategies systematically monitor variations in target and
neighbouring structures to inform treatment-plan modification during radiotherapy. This is …

The excellent soft-tissue contrast of magnetic resonance (MR) images, and the speed and
frequency with which the patient can be imaged, allow clear visualization of the target and …

Online adaptive treatment procedures in magnetic resonance (MR)-guided radiotherapy
(MRgRT) allow compensating for inter-fractional anatomical variations in the patient. Clinical …

Introduction Magnetic resonance guided radiotherapy (MRgRT) allows daily adaptation of
treatment plans to compensate for positional changes of target volumes and organs at risk …

MRI-guided radiotherapy (MRIgRT) is a highly complex treatment modality, allowing
adaptation to anatomical changes occurring from one treatment day to the other (inter …
