The impact of 2D cine MR imaging parameters on automated tumor and organ localization for MR-guided real-time adaptive radiotherapy.
(IOP PUBLISHING LTD, 2018-11-22)
2D cine MR imaging may be utilized to monitor rapidly moving tumors and organs-at-risk for real-time adaptive radiotherapy. This study systematically investigates the impact of geometric imaging parameters on the ability ...
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 ...
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 ...
