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 ...
