The integration of adaptive radiation therapy (ART), or modifying the treatment plan during
the treatment course, is becoming more widely available in clinical practice. ART offers …

Radiotherapy (RT) aims to deliver a spatially conformal dose of radiation to tumours while
maximizing the dose sparing to healthy tissues. However, the internal patient anatomy is …

The integration of 1.5 T MRI functionality with a radiotherapy linear accelerator (linac) has
been pursued since 1999 by the UMC Utrecht in close collaboration with Elekta and Philips …

The integration of magnetic resonance imaging (MRI) for guidance in external beam
radiotherapy has faced significant research and development efforts in recent years. The …

Background The targeting accuracy of proton therapy (PT) for moving soft-tissue tumours is
expected to greatly improve by real-time magnetic resonance imaging (MRI) guidance. The …

Purpose To evaluate prostate intrafraction motion using MRI during the full course of online
adaptive MR-Linac radiotherapy (RT) fractions, in preparation of MR-guided extremely …

Background and purpose In this report, we describe our implementation and initial clinical
experience using 4D-MRI driven MR-guided online adaptive radiotherapy (MRgOART) for …

Magnetic resonance imaging (MRI) has been widely used in combination with computed
tomography (CT) radiation therapy because MRI improves the accuracy and reliability of …

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