Comment on the use of GOES solar proton data and spectra in solar proton dose calculations

Radiation Measurements, 1999
There is a need to understand the calibration and response of the GOES solar particle detectors since the GOES data are being used to evaluate high energy solar particle events. We share some of our experience in utilizing these data in the analysis of solar particle ground-level events (GLEs).

Independent dose calculations for commissioning, quality assurance and dose reconstruction of PBS proton therapy

Physics in Medicine and Biology, 2015
Pencil beam scanning proton therapy allows the delivery of highly conformal dose distributions by delivering several thousand pencil beams. These beams have to be individually optimised and accurately delivered requiring a significant quality assurance workload.

Dose calculations in proton beams: range straggling corrections and energy scaling

Physics in Medicine and Biology, 1995
Three-dimensional dose planning systems employing accurate proton transport algorithms are essential for calculating absorbed dose distributions in proton therapy. In this paper, a pencil beam algorithm for the transport of protons in materials of interest for radiation therapy is developed.

SU‐E‐T‐579: Effect of Dose Calculation Grid Size On Proton Dose Calculation

Medical Physics, 2013
Purpose: The effect of dose calculation grid size for highly conformal proton planning is evaluated for the first time. Our goal is to find the optimal dose calculation grid size for different cases to increase the treatment planning efficiency while maintaining the dose calculation accuracy within clinical tolerance.

Dose calculations for clinical proton broad beams by GEANT4

2009
The aim of this work is to develop a dose calculation engine for clinical proton beams based on a Monte- Carlo code, GEANT4 (G4 dose engine), and to evaluate the dose distributions calculated by the engine by comparing with the measurements and the calculations of the pencil-beam algorithm (PBA).
