Principal component analysis fosr fast and model-free denoising of multi b-value diffusion-weighted MR images.
(IOP PUBLISHING LTD, 2019-04-09)
Despite the utility of tumour characterisation using quantitative parameter maps from multi-b-value diffusion-weighted MRI (DWI), clinicians often prefer the use of the image with highest diffusion-weighting (b-value), for ...
Synthetic 4D-CT of the thorax for treatment plan adaptation on MR-guided radiotherapy systems.
(IOP PUBLISHING LTD, 2019-05-23)
MR-guided radiotherapy treatment planning utilises the high soft-tissue contrast of MRI to reduce uncertainty in delineation of the target and organs at risk. Replacing 4D-CT with MRI-derived synthetic 4D-CT would support ...
MRI commissioning of 1.5T MR-linac systems - a multi-institutional study.
(ELSEVIER IRELAND LTD, 2019-03-01)
BACKGROUND: Magnetic Resonance linear accelerator (MR-linac) systems represent a new type of technology that allows for online MR-guidance for high precision radiotherapy (RT). Currently, the first MR-linac installations ...
Realizing the potential of magnetic resonance image guided radiotherapy in gynaecological and rectal cancer.
(BRITISH INST RADIOLOGY, 2019-05-14)
CT-based radiotherapy workflow is limited by poor soft tissue definition in the pelvis and reliance on rigid registration methods. Current image-guided radiotherapy and adaptive radiotherapy models therefore have limited ...
