Commissioning an Exradin W2 plastic scintillation detector for clinical use in small radiation fields.

Journal Article J Appl Clin Med Phys · August 2022 PURPOSE: The purpose of this work is to evaluate the Standard Imaging Exradin W2 plastic scintillation detector (W2) for use in the types of fields used for stereotactic radiosurgery. METHODS: Prior to testing the W2 in small fields, the W2 was evaluated i ... Full text Link to item Cite

Diagnosing atmospheric communication of a sealed monitor chamber.

Journal Article J Appl Clin Med Phys · August 2020 Daily output variations of up to ┬▒2% were observed for a protracted time on a Varian TrueBeam┬« STx; these output variations were hypothesized to be the result of atmospheric communication of the sealed monitor chamber. Daily changes in output relative to b ... Full text Link to item Cite

Radiation treatment planning and delivery strategies for a pregnant brain tumor patient.

Journal Article J Appl Clin Med Phys · September 2018 The management of a pregnant patient in radiation oncology is an infrequent event requiring careful consideration by both the physician and physicist. The aim of this manuscript was to highlight treatment planning techniques and detail measurements of feta ... Full text Link to item Cite

Comparison between proton boron fusion therapy (PBFT) and boron neutron capture therapy (BNCT): a monte carlo study.

Journal Article Oncotarget · June 13, 2017 The aim of this study is to compare between proton boron fusion therapy (PBFT) and boron neutron capture therapy (BNCT) and to analyze dose escalation using a Monte Carlo simulation. We simulated a proton beam passing through the water with a boron uptake ... Full text Link to item Cite

Efficient independent planar dose calculation for FFF IMRT QA with a bivariate Gaussian source model.

Journal Article J Appl Clin Med Phys · March 2017 The aim of this study is to perform a direct comparison of the source model for photon beams with and without flattening filter (FF) and to develop an efficient independent algorithm for planar dose calculation for FF-free (FFF) intensity-modulated radioth ...

Technical Note: Impact of the geometry dependence of the ion chamber detector response function on a convolution-based method to address the volume averaging effect.

Journal Article Med Phys · May 2016 PURPOSE: To investigate the geometry dependence of the detector response function (DRF) of three commonly used scanning ionization chambers and its impact on a convolution-based method to address the volume averaging effect (VAE). METHODS: A convolution-ba ... Full text Link to item Cite

Parameterization of photon beam dosimetry for a linear accelerator.

Journal Article Med Phys · February 2016 PURPOSE: In radiation therapy, accurate data acquisition of photon beam dosimetric quantities is important for (1) beam modeling data input into a treatment planning system (TPS), (2) comparing measured and TPS modeled data, (3) the quality assurance proce ...

A novel convolution-based approach to address ionization chamber volume averaging effect in model-based treatment planning systems.

Journal Article Phys Med Biol · August 21, 2015 The ionization chamber volume averaging effect is a well-known issue without an elegant solution. The purpose of this study is to propose a novel convolution-based approach to address the volume averaging effect in model-based treatment planning systems (T ... Full text Link to item Cite
