Development of a methodology to study the effect of magnetic field on dose distributions in an MR-linac, using PRESAGE (R) and Monte Carlo calculations
Costa, F; Doran, S; Nill, S; Duane, S; Shipley, D; et al. (IOP PUBLISHING LTD, 2017-01-01) -
Edge effects in 3D dosimetry: characterisation and correction of the non-uniform dose response of PRESAGE®.
Costa, F; Doran, SJ; Hanson, IM; Adamovics, J; Nill, S; et al. (IOP PUBLISHING LTD, 2020-05-04)Previous work has shown that PRESAGE® can be used successfully to perform 3D dosimetric measurements of complex radiotherapy treatments. However, measurements near the sample edges are known to be difficult to achieve. ... -
Investigating the effect of a magnetic field on dose distributions at phantom-air interfaces using PRESAGE® 3D dosimeter and Monte Carlo simulations.
Costa, F; Doran, SJ; Hanson, IM; Nill, S; Billas, I; et al. (IOP PUBLISHING LTD, 2018-02-26)Dosimetric quality assurance (QA) of the new Elekta Unity (MR-linac) will differ from the QA performed of a conventional linac due to the constant magnetic field, which creates an electron return effect (ERE). In this work ... -
Three-dimensional dose verification of adaptive radiotherapy at an MR-linac
Oelfke, U; Costa, F (Institute of Cancer Research (University Of London), 2020-04-30)The vision of accurate real-time image-guided radiotherapy (RT) has led to the development of MR-Linacs consisting of MRI scanners integrated within RT treatment units. The safe clinical operation of these devices requires ...
