4D-MRI for thoracic radiotherapy treatment planning and guidance on an MR-linac
Leach, M; Freedman, J; Leach, MLung cancer currently has a poor prognosis in England and Wales with only 10% of adults surviving five years or more after diagnosis. The poor survival rate demonstrates the need to improve contemporary treatment approaches ... -
Super-resolution T2-weighted 4D MRI for image guided radiotherapy.
Freedman, JN; Collins, DJ; Gurney-Champion, OJ; McClelland, JR; Nill, S; et al. (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 ... -
Synthetic 4D-CT of the thorax for treatment plan adaptation on MR-guided radiotherapy systems.
Freedman, JN; Bainbridge, HE; Nill, S; Collins, DJ; Kachelrieß, M; et al. (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 ... -
T2-Weighted 4D Magnetic Resonance Imaging for Application in Magnetic Resonance-Guided Radiotherapy Treatment Planning.
Freedman, JN; Collins, DJ; Bainbridge, H; Rank, CM; Nill, S; et al. (LIPPINCOTT WILLIAMS & WILKINS, 2017-10-01)OBJECTIVES: The aim of this study was to develop and verify a method to obtain good temporal resolution T2-weighted 4-dimensional (4D-T2w) magnetic resonance imaging (MRI) by using motion information from T1-weighted 4D ...
