Guo K, Ingleby H, Van Uytven E, Elbakri I, Van Beek T, McCurdy B
J Appl Clin Med Phys
. 2021 Oct;
22(11):99-114.
PMID: 34697889
On-treatment EPID images are contaminated with patient-generated scattered photons. If this component can be accurately estimated, its effect can be removed, and therefore a corresponding in vivo patient dose estimate...

Kutuzov I, Van Beek T, McCurdy B
J Appl Clin Med Phys
. 2021 May;
22(7):110-120.
PMID: 34021713
Purpose: There is an increased interest in using non-coplanar beams for radiotherapy, including SBRT and SRS. This approach can significantly reduce doses to organs-at-risk, however, it requires stringent quality assurance,...

Guo K, Ingleby H, Van Uytven E, Elbakri I, Van Beek T, McCurdy B
Phys Med Biol
. 2020 Jun;
65(18):185008.
PMID: 32516759
In vivo dosimetry methods can verify the prescription dose is delivered to the patient during treatment. Unfortunately, in exit dosimetry, the megavoltage image is contaminated with patient-generated scattered photons. However,...

Phys Med Biol
. 2020 Mar;
65(9):09NT02.
PMID: 32160599
Scattered radiation unavoidably generated in the patient will negatively impact both kilovoltage (KV) and megavoltage (MV) imaging applications. Recently, 'hybrid' methods (i.e. combining analytical and Monte Carlo (MC) techniques) are...

Van Uytven E, Van Beek T, McCowan P, Chytyk-Praznik K, Greer P, McCurdy B
Med Phys
. 2015 Dec;
42(12):6945-54.
PMID: 26632050
Purpose: Radiation treatments are trending toward delivering higher doses per fraction under stereotactic radiosurgery and hypofractionated treatment regimens. There is a need for accurate 3D in vivo patient dose verification...

Woodruff H, Fuangrod T, Van Uytven E, McCurdy B, Van Beek T, Bhatia S, et al.
Int J Radiat Oncol Biol Phys
. 2015 Oct;
93(3):516-22.
PMID: 26460993
Purpose: Gantry-mounted megavoltage electronic portal imaging devices (EPIDs) have become ubiquitous on linear accelerators. WatchDog is a novel application of EPIDs, in which the image frames acquired during treatment are...
