Beam coordinate transformations from DICOM to DOSXYZnrc

Physics in Medicine and Biology, 2012
Digital imaging and communications in medicine (DICOM) format is the de facto standard for communications between therapeutic and diagnostic modalities. A plan generated by a treatment planning system (TPS) is often exported in DICOM format. BEAMnrc/DOSXYZnrc is a widely used Monte Carlo (MC) package for modelling the Linac head and simulating dose ...

The Use of DOSXYZnrc to Simulate a Voxel Phantom in Radiation Protection

Communications in Computer and Information Science, 2011
Very significant advancements were presented during the years with computational phantom, passing from stylized analytical human models to realistic voxel models based on computed tomography scans or MRI scans ,and finally to advanced surface-geometry models. This paper presents an investigation on the description of phantom based on the DOSXYZnrc code

DOSSCORE: an accelerated DOSXYZnrc code with an efficient stepping algorithm and scoring grid

Physics in Medicine and Biology, 2004
DOSSCORE is an accelerated version of DOSXYZnrc that allows photons to cross voxel boundaries of the same medium and utilizes a separate scoring grid superimposed on the geometrical grid. Two different stepping algorithms, the hownear method and the scaling method are implemented in DOSSCORE.

Voxel dosimetry: Comparison of MCNPX and DOSXYZnrc Monte Carlo codes in patient specific phantom calculations

Technology and Health Care, 2017
INTRODUCTION: Dose evaluation with two Monte Carlo codes using patient specific voxel phantom is presented in this paper. We employ both MCNPX and DOSXYZnrc to perform dosimetry for mathematical voxel phantoms generated by our in-house developed voxel phantom generator and EGSnrc/CTCreate respectively.

Interface software for DOSXYZnrc Monte Carlo dose evaluation on a commercial radiation treatment planning system

Radiation Medicine, 2007
As the conventional graphical user interface (GUI) associated with DOSXYZnrc or BEAMnrc is unable to define specific structures such as gross tumor volume (GTV) on computed tomography (CT) data, the quantitative analysis of doses in the form of dose-volume histograms (DVHs) is difficult.

Two new DOSXYZnrc sources for 4D Monte Carlo simulations of continuously variable beam configurations, with applications to RapidArc, VMAT, TomoTherapy and CyberKnife

Physics in Medicine and Biology, 2010
We present two new Monte Carlo sources for the DOSXYZnrc code, which can be used to compute dose distributions due to continuously variable beam configurations. These sources support a continuously rotating gantry and collimator, dynamic multileaf collimator (MLC) motion, variable monitor unit (MU) rate, couch rotation and translation in any direction,

Validation of Monte Carlo simulation of 6 MV photon beam produced by Varian Clinac 2100 linear accelerator using BEAMnrc code and DOSXYZnrc code

Physics of Particles and Nuclei Letters, 2017
The Monte Carlo model for the photon-beam output from the Varian Clinac 2100 linear accelerator was validated to compare the calculated to measured PDD and beam dose profiles The Monte Carlo calculation method is considered to be the most accurate method for dose calculation in radiotherapy.
