Purpose The dosimetry of focal high-dose-rate prostate brachytherapy was assessed. Dose
volume histogram parameters, robustness to source position errors, and Monte Carlo (MC) …

Abstract egs_brachy is a versatile and fast Monte Carlo (MC) code for brachytherapy
applications. It is based on the EGSnrc code system, enabling simulation of photons and …

Background: The Monte Carlo (MC) method is not only used for dose calculations around
brachytherapy sources but also for benchmarking treatment planning systems (TPS) …

PURPOSE: Three types of radiation sources are employed currently in the radiation
treatment of prostate cancer, namely, external, implant, and high-dose-rate (HDR) sources …

This paper presents a preliminary study on multiple‐radionuclide sources for brachytherapy.
An adaptation of the AAPM TG‐43U1 formalism is proposed in order to derive the dosimetry …

• Dosimetry o Dosimetry in accordance with 2004 AAPM TG-43U1 methodology o 2-D
source characterization preferred only when source orientation is evident o The prescribed …

Purpose: Radioactive seed orientations are usually ignored in clinical brachytherapy
dosimetry for prostate implants. Associated with the anisotropic dose distribution of seeds …

A Monte Carlo model has been developed using MCNP5 to simulate the Nucletron Ir-192
HDR source in order to investigate the influence of tissue heterogeneities on dose …

Purpose: To validate Gpumcd, a new package for fast Monte Carlo dose calculations based
on the GPU (graphics processing unit), as a tool for low‐energy single seed brachytherapy …

Purpose The purpose of this study was to evaluate the impact of dose reporting schemes
and tissue/applicator heterogeneities for 192Ir‐, 75Se‐, and 169Yb‐based MRI‐guided …
