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 ...
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 ...
MRI-guided lung SBRT: Present and future developments.
(ELSEVIER SCI LTD, 2017-12-01)
Stereotactic body radiotherapy (SBRT) is rapidly becoming an alternative to surgery for the treatment of early-stage non-small cell lung cancer patients. Lung SBRT is administered in a hypo-fractionated, conformal manner, ...
Super-resolution T2-weighted 4D MRI for image guided radiotherapy.
(ELSEVIER IRELAND LTD, 2018-12-01)
BACKGROUND AND PURPOSE: The superior soft-tissue contrast of 4D-T2w MRI motivates its use for delineation in radiotherapy treatment planning. We address current limitations of slice-selective implementations, including ...
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 ...
