A dosimetric comparison of real-time adaptive and non-adaptive radiotherapy: A multi-institutional study encompassing robotic, gimbaled, multileaf collimator and couch tracking.
(ELSEVIER IRELAND LTD, 2016-04-01)
PURPOSE: A study of real-time adaptive radiotherapy systems was performed to test the hypothesis that, across delivery systems and institutions, the dosimetric accuracy is improved with adaptive treatments over non-adaptive ...
Novel adaptive beam-dependent margins for additional OAR sparing.
(IOP PUBLISHING LTD, 2018-10-29)
Margins are employed in radiotherapy treatment planning to mitigate the dosimetric effects of geometric uncertainties for the clinical target volume (CTV). Unfortunately, whilst the use of margins can increase the probability ...
Magnetic Resonance Imaging-Guided Adaptive Radiation Therapy: A "Game Changer" for Prostate Treatment?
(ELSEVIER SCIENCE INC, 2018-02-01)
Radiation therapy to the prostate involves increasingly sophisticated delivery techniques and changing fractionation schedules. With a low estimated α/β ratio, a larger dose per fraction would be beneficial, with moderate ...
Assessment of MLC tracking performance during hypofractionated prostate radiotherapy using real-time dose reconstruction.
(IOP PUBLISHING LTD, 2016-02-21)
By adapting to the actual patient anatomy during treatment, tracked multi-leaf collimator (MLC) treatment deliveries offer an opportunity for margin reduction and healthy tissue sparing. This is assumed to be especially ...
Online dose reconstruction for tracked volumetric arc therapy: Real-time implementation and offline quality assurance for prostate SBRT.
(WILEY, 2017-08-20)
PURPOSE: Firstly, this study provides a real-time implementation of online dose reconstruction for tracked volumetric arc therapy (VMAT). Secondly, this study describes a novel offline quality assurance tool, based on ...
Evaluation of a multi-atlas CT synthesis approach for MRI-only radiotherapy treatment planning.
(ELSEVIER SCI LTD, 2017-03-01)
BACKGROUND AND PURPOSE: Computed tomography (CT) imaging is the current gold standard for radiotherapy treatment planning (RTP). The establishment of a magnetic resonance imaging (MRI) only RTP workflow requires the ...
A novel probabilistic approach to generating PTV with partial voxel contributions.
(IOP PUBLISHING LTD, 2017-06-21)
Radiotherapy treatment planning for use with high-energy photon beams currently employs a binary approach in defining the planning target volume (PTV). We propose a margin concept that takes the beam directions into account, ...
First evaluation of the feasibility of MLC tracking using ultrasound motion estimation.
(WILEY, 2016-08-01)
PURPOSE: To quantify the performance of the Clarity ultrasound (US) imaging system (Elekta AB, Stockholm, Sweden) for real-time dynamic multileaf collimator (MLC) tracking. METHODS: The Clarity calibration and quality ...
Evaluation of therapeutic radiographer contouring for magnetic resonance image guided online adaptive prostate radiotherapy.
(ELSEVIER IRELAND LTD, 2023-03-01)
BACKGROUND AND PURPOSE: The implementation of MRI-guided online adaptive radiotherapy has facilitated the extension of therapeutic radiographers' roles to include contouring, thus releasing the clinician from attending ...
