Daily Intravoxel Incoherent Motion (IVIM) In Prostate Cancer Patients During MR-Guided Radiotherapy-A Multicenter Study.
(FRONTIERS MEDIA SA, 2021-08-13)
PURPOSE: Daily quantitative MR imaging during radiotherapy of cancer patients has become feasible with MRI systems integrated with linear accelerators (MR-linacs). Quantitative images could be used for treatment response ...
Longitudinal Stability of MRI QA up to Two Years on Eight Clinical 1.5 T MR-Linacs
(FRONTIERS MEDIA SA, 2022-06-13)
<jats:p>MR-guided radiotherapy on hybrid MR-Linacs exploits the excellent soft-tissue contrast of MRI to deliver daily adaptive precision radiotherapy. Geometric fidelity and long-term stability of MRI components are ...
Evaluation of MRI-derived surrogate signals to model respiratory motion.
(IOP PUBLISHING LTD, 2020-07-01)
An MR-Linac can provide motion information of tumour and organs-at-risk before, during, and after beam delivery. However, MR imaging cannot provide real-time high-quality volumetric images which capture breath-to-breath ...
Tumour auto-contouring on 2d cine MRI for locally advanced lung cancer: A comparative study.
(ELSEVIER IRELAND LTD, 2017-12-01)
BACKGROUND AND PURPOSE: Radiotherapy guidance based on magnetic resonance imaging (MRI) is currently becoming a clinical reality. Fast 2d cine MRI sequences are expected to increase the precision of radiation delivery by ...
Respiratory motion modelling for MR-guided lung cancer radiotherapy: model development and geometric accuracy evaluation.
(IOP Publishing Ltd, 2024-02-19)
Objective.Respiratory motion of lung tumours and adjacent structures is challenging for radiotherapy. Online MR-imaging cannot currently provide real-time volumetric information of the moving patient anatomy, therefore ...
Accelerating 4D image reconstruction for magnetic resonance-guided radiotherapy.
(ELSEVIER, 2023-07-01)
BACKGROUND AND PURPOSE: Physiological motion impacts the dose delivered to tumours and vital organs in external beam radiotherapy and particularly in particle therapy. The excellent soft-tissue demarcation of 4D magnetic ...
