Evaluation of radiotherapy techniques for radical treatment of lateralised oropharyngeal cancers : Dosimetry and NTCP.
(URBAN & VOGEL, 2016-08-01)
AIM: The aim of this study was to investigate potential advantages and disadvantages of three-dimensional conformal radiotherapy (3DCRT), multiple fixed-field intensity-modulated radiotherapy (IMRT) and volumetric-modulated ...
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 ...
Treating locally advanced lung cancer with a 1.5T MR-Linac - Effects of the magnetic field and irradiation geometry on conventionally fractionated and isotoxic dose-escalated radiotherapy.
(ELSEVIER IRELAND LTD, 2017-11-01)
PURPOSE: This study investigates the feasibility and potential benefits of radiotherapy with a 1.5T MR-Linac for locally advanced non-small cell lung cancer (LA NSCLC) patients. MATERIAL AND METHODS: Ten patients with LA ...
A kernel-based dose calculation algorithm for kV photon beams with explicit handling of energy and material dependencies.
(BRITISH INST RADIOLOGY, 2017-01-01)
OBJECTIVE: Mimicking state-of-the-art patient radiotherapy with high-precision irradiators for small animals is expected to advance the understanding of dose-effect relationships and radiobiology in general. We work on the ...
Geometric and dosimetric evaluations of atlas-based segmentation methods of MR images in the head and neck region.
(IOP Publishing, 2018-07-11)
Owing to its excellent soft-tissue contrast, magnetic resonance (MR) imaging has found an increased application in radiation therapy (RT). By harnessing these properties for treatment planning, automated segmentation methods ...
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 ...
