A new grid-based Boltzmann equation solver, Acuros™, was developed specifically for
performing accurate and rapid radiotherapy dose calculations. In this study we …

Purpose: The deterministic Acuros XB (AXB) algorithm was recently implemented in the
Eclipse treatment planning system. The goal of this study was to compare AXB performance …

Dose calculation plays an important role in the accuracy of radiotherapy treatment planning
and beam delivery. The Monte Carlo (MC) method is capable of achieving the highest …

Several studies have shown that removal of the flattening filter from the treatment head of a
clinical accelerator increases the dose rate and changes the lateral profile in radiation …

Purpose: To create an accurate 6 MV Monte Carlo simulation phase space for the Varian
TrueBeam treatment head geometry imported from cad (computer aided design) without …

This study develops and tests a method to compute dosimetric images for an amorphous
silicon flat‐panel detector so that an accurate quantitative comparison between measured …

Our aim in the present study was to investigate the effects of initial electron beam
characteristics on Monte Carlo calculated absorbed dose distribution for a linac 6 MV photon …

Dose to the patient outside of the treatment field is important when evaluating the outcome of
radiotherapy treatments. However, determining out‐of‐field doses for any particular …

There is a serious and growing concern about the increased risk of radiation-induced
second cancers and late tissue injuries associated with radiation treatment. To better …

In conventional clinical linear accelerators, the flattening filter scatters and absorbs a large
fraction of primary photons. Increasing the beam‐on time, which also increases the out‐of …
