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 ...
