Anatomical Deformation Due to Horizontal Rotation: Towards Gantry-Free Radiation Therapy
Buckley, J; Rai, R; Liney, G; Dowling, J; Holloway, L; Metcalfe, P; Keall, PPublished 2019-01-01Gantry-free radiation therapy systems may be simpler and more cost effective, particularly for MRI-guided photon or hadron therapy. This study aims to understand and quantify anatomical deformations caused by horizontal ...Open AccessArticle -
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 -
Measurements of human tolerance to horizontal rotation within an MRI scanner: Towards gantry-free radiation therapy.
Buckley, J; Smith, A; Sidhom, M; Rai, R; Liney, G; Dowling, J; Metcalfe, P; Holloway, L; Keall, PPublished 2021Introduction: Recent advances in image guidance and adaptive radiotherapy could enable gantry-free radiotherapy using patient rotation. Gantry-free radiotherapy could substantially reduce the cost of radiotherapy systems ...Open AccessArticle -
Pelvic organ motion and dosimetric implications during horizontal patient rotation for prostate radiation therapy.
Buckley, J; Dowling, J; Sidhom, M; Liney, G; Rai, R; Metcalfe, p; Holloway, L; Keall, PPublished 2021Purpose: Gantry-free radiation therapy systems utilizing patient rotation would be simpler and more cost effective than the conventional gantry-based systems. Such a system could enable the expansion of radiation therapy ...Open AccessArticle -
Radiotherapy beyond cancer: target localization in real-time MRI and treatment planning for cardiac radiosurgery.
Ipsen, S; Blanck, O; Oborn, B; Bode, F; Liney, G; Hunold, P; Rades, D; Schweikard, A; Keall, PPublished 2014-12-01PURPOSE: Atrial fibrillation (AFib) is the most common cardiac arrhythmia that affects millions of patients world-wide. AFib is usually treated with minimally invasive, time consuming catheter ablation techniques. While ...Open AccessArticle -
Technical Note: Experimental Characterization of the Dose Deposition in Parallel MRI-linacs at Various Magnetic Field Strengths
Begg, J; Alnaghy, S; Causer, T; Alharthi, T; George, A; Glaubes, L; Dong, B; Goozee, G; Keall, P; Jelen, U; Liney, G; Holloway, LPublished 2019-01-01Purpose: Dose deposition measurements for parallel MRI-linacs have previously only shown comparisons between 0 T and a single available magnetic field. The Australian MRI-Linac consists of a magnet coupled with a dual ...Open AccessArticle -
