Experimental characterisation of the magnetic field correction factor,k->B,for Roos chambers in a parallel MRI-linac.
Begg, J; Jelen, U; Keall, P; Liney, G; Holloway, LPublished 2022Objective. Reference dosimetry on an MRI-linac requires a chamber specific magnetic field correction factor,kB⃗.This work aims to measure the correction factor for a parallel plate chamber on a parallel MRI-linac. Approach. ...Open AccessArticle -
