Fast CPU-based Monte Carlo simulation for radiotherapy dose calculation.
(2015-08)
Monte-Carlo (MC) simulations are considered to be the most accurate method for calculating dose distributions in radiotherapy. Its clinical application, however, still is limited by the long runtimes conventional implementations ...
Calculation of absorbed dose in radiotherapy by solution of the linear Boltzmann transport equations.
(2019-01-10)
Over the last decade, dose calculations which solve the linear Boltzmann transport equations have been introduced into clinical practice and are now in widespread use. However, knowledge in the radiotherapy community ...
Using dual-energy x-ray imaging to enhance automated lung tumor tracking during real-time adaptive radiotherapy.
(WILEY, 2015-12-01)
PURPOSE: Real-time, markerless localization of lung tumors with kV imaging is often inhibited by ribs obscuring the tumor and poor soft-tissue contrast. This study investigates the use of dual-energy imaging, which can ...
Introducing the concept of spiral microbeam radiation therapy (spiralMRT).
(IOP PUBLISHING LTD, 2019-03-08)
MOTIVATION: With interlaced microbeam radiation therapy (MRT) a first kilovoltage radiotherapy (RT) concept combining spatially fractionated entrance beams and homogeneous dose distribution at the target exists. However, ...
Line focus x-ray tubes-a new concept to produce high brilliance x-rays.
(IOP PUBLISHING LTD, 2017-10-27)
Currently hard coherent x-ray radiation at high photon fluxes can only be produced with large and expensive radiation sources, such as 3[Formula: see text] generation synchrotrons. Especially in medicine, this limitation ...
Investigating the effect of a magnetic field on dose distributions at phantom-air interfaces using PRESAGE® 3D dosimeter and Monte Carlo simulations.
(IOP PUBLISHING LTD, 2018-02-26)
Dosimetric quality assurance (QA) of the new Elekta Unity (MR-linac) will differ from the QA performed of a conventional linac due to the constant magnetic field, which creates an electron return effect (ERE). In this work ...
Alanine dosimetry in strong magnetic fields: use as a transfer standard in MRI-guided radiotherapy.
(IOP PUBLISHING LTD, 2020-06-03)
Reference dosimetry in the presence of a strong magnetic field is challenging. Ionisation chambers have shown to be strongly affected by magnetic fields. There is a need for robust and stable detectors in MRI-guided ...
Towards real-time photon Monte Carlo dose calculation in the cloud.
(IOP Publishing Ltd, 2017-06-07)
Near real-time application of Monte Carlo (MC) dose calculation in clinic and research is hindered by the long computational runtimes of established software. Currently, fast MC software solutions are available utilising ...
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 ...
