1. MR-guided adaptive stereotactic radiotherapy: A new paradigm in radiotherapy

Physica Medica, 2017
Introduction In May 2016 we have implemented stereotactic MR-guided adaptive radiation therapy at the VU University Medical Center by using the MRIdian system (ViewRay, Inc.). Our approach consists of: (1) MR-guided tumor setup; (2) daily online plan adaptation to account for inter-fractional changes; (3) patient-specific QA; (4) gated treatment ...

Role of MR-guided Radiotherapy (MRgRT) in Colorectal Cancer

Current Colorectal Cancer Reports, 2021
The current standard treatment for locally advanced or metastatic colorectal cancer often includes radiotherapy delivered under computed tomography (CT)–based image guidance. Magnetic resonance–guided radiotherapy (MRgRT) offers a substantial improvement in target and adjacent organ visualization and allows for real-time imaging throughout treatment to

End-to-end test for fractionated online adaptive MR-guided radiotherapy using a deformable anthropomorphic pelvis phantom

Physics in Medicine and Biology, 2021
Objective. In MR-guided radiotherapy (MRgRT) for prostate cancer treatments inter-fractional anatomy changes such as bladder and rectum fillings may be corrected by an online adaption of the treatment plan.

Prostate diffusion-weighted imaging (DWI) in MR-guided radiotherapy: Reproducibility assessment on 1.5 T MR-Linac and 1.5 T MR-simulator.

Magnetic Resonance Imaging
PURPOSE Diffusion-weighted imaging (DWI) holds promise for image-guided radiotherapy (MRgRT) in prostate cancer. However, challenges persist due to image distortion, artifacts, and apparent diffusion coefficient (ADC) reproducibility issues.
