Phys Med Biol
. 2023 Jan;
68(3).
PMID: 36595255
The aim of this work was to develop and validate a method for remote dosimetric auditing that enables dose-volume histogram parameter comparisons of measured and planned dose in the patient...

Phys Med
. 2022 Oct;
103:108-118.
PMID: 36272328
Purpose: The first aim was to generate and compare synthetic-CT (sCT) images using a conditional generative adversarial network (cGAN) method (Pix2Pix) for MRI-only prostate radiotherapy planning by testing several generators,...

Roach D, Jameson M, Dowling J, Ebert M, Greer P, Kennedy A, et al.
Phys Med Biol
. 2018 Jan;
63(3):035001.
PMID: 29300184
Many similarity metrics exist for inter-observer contouring variation studies, however no correlation between metric choice and prostate cancer radiotherapy dosimetry has been explored. These correlations were investigated in this study....

Seregni M, Paganelli C, Lee D, Greer P, Baroni G, Keall P, et al.
Phys Med Biol
. 2016 Jan;
61(2):872-87.
PMID: 26740517
In-room cine-MRI guidance can provide non-invasive target localization during radiotherapy treatment. However, in order to cope with finite imaging frequency and system latencies between target localization and dose delivery, tumour...

Phys Med Biol
. 2015 Feb;
60(5):1793-805.
PMID: 25658193
Collected real-life clinical target volume (CTV) displacement data show that some patients undergoing external beam radiotherapy (EBRT) demonstrate significantly more fraction-to-fraction variability in their displacement ('random error') than others. This...

Br J Radiol
. 2014 Jul;
87(1042):20140325.
PMID: 25061776
Objective: To eliminate the effects of body deformation for MR-based prostate treatment planning, coil mounts are essential. In this study, we evaluated the effect of the coil set-up on image...

Phys Med
. 2013 Nov;
30(3):326-30.
PMID: 24176533
This study is part of a project concerned with real-time EPID-based verification of the incremental dose delivered during IMRT radiation treatments. Three automated Monte-Carlo methods are devised to calculate the...

Med Phys
. 2013 Mar;
40(3):031713.
PMID: 23464308
Purpose: Dosimetric verification of radiation therapy is crucial when delivering complex treatments like intensity modulated radiation therapy (IMRT) or volumetric modulated arc therapy (VMAT. Pretreatment verification, characterized by methods applied...

57(9):2743-55.
PMID: 22507828
Early approaches to characterizing errors in target displacement during a fractionated course of radiotherapy assumed that the underlying fraction-to-fraction variability in target displacement, known as the 'treatment error' or 'random...

PMID: 22038292
The long-term stability of three clinical electronic portal imaging devices (EPIDs) was studied to determine if longer times between calibrations can be justified. This would make alternatives to flood-field calibration...
