Background T2* mapping can characterize tumor hypoxia, which may be associated with
resistance to therapy. Acquiring T2* maps during MR‐guided radiotherapy could inform …

Abstract Background and Purpose The heart is important in radiotherapy either as target or
organ at risk. Quantitative T 1 and T 2 cardiac magnetic resonance imaging (qMRI) may aid …

Background and purpose Magnetic resonance imaging (MRI)-Linac systems combine
simultaneous MRI with radiation delivery, allowing treatments to be guided by anatomically …

Online adaptive MR-guided radiation therapy improves treatment quality at the expense of
considerable longer treatment time. The treatment lengthening partially originates from the …

For tumor tracking in MRI-guided radiotherapy it is important to minimize the latency
between the moment of anatomic change and its appearance on the MR image. By using a …

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: MR-guided Radiation Therapy (MRgRT) allows for high-precision radiotherapy
under real-time MR visualization. This enables margin reduction and subsequent dose …

abstract 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 …

Hybrid MRI linear accelerators (MR-linacs) enable real-time image guidance during
radiotherapy. Under real-time MRI, a compromise must be found between spatio-temporal …

Adaptive radiotherapy (RT) is a concept of repeated replanning according to changes in the
tumor shape or normal anatomy during a course of fractionated RT. It is mostly applied in an …
