Adapting to the motion of multiple independent targets using multileaf collimator tracking for locally advanced prostate cancer: Proof of principle simulation study.
Published 2021Purpose: For patients with locally advanced cancer, multiple targets are treated simultaneously with radiotherapy. Differential motion between targets can compromise the treatment accuracy, yet there are currently no methods ...Open AccessArticle -
Dose-based optimisation for multi-leaf collimator tracking during radiation therapy.
Published 2021Motion in the patient anatomy causes a reduction in dose delivered to the target, while increasing dose to healthy tissue. Multi-leaf collimator (MLC) tracking has been clinically implemented to adapt dose delivery to ...Open AccessArticle -
The first prospective implementation of markerless lung target tracking in an experimental quality assurance procedure on a standard linear accelerator.
Published 2020-01-01The ability to track tumour motion without implanted markers on a standard linear accelerator (linac) could enable wide access to real-time adaptive radiotherapy for cancer patients. We previously have retrospectively ...Open AccessArticle -
Pelvic organ motion and dosimetric implications during horizontal patient rotation for prostate radiation therapy.
Published 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 -
Quantification of the geometric uncertainty when using implanted markers as a surrogate for lung tumor motion.
Published 2021Background: Fiducial markers are used as surrogates for tumor location during radiation therapy treatment. Developments in lung fiducial marker and implantation technology have provided a means to insert markers endobronchially ...Open AccessArticle
