Particle therapy facilities often require Monte Carlo (MC) simulations to overcome intrinsic
limitations of analytical treatment planning systems (TPS) related to the description of the …

Stereotactic body radiation therapy (SBRT) has been increasingly used as an efficacious
treatment modality for early‐stage non‐small cell lung cancer. The accuracy of dose …

Radiotherapy calculations often involve complex geometries such as interfaces between
materials of vastly differing atomic number, such as lung, bone and/or air interfaces. Monte …

The accuracy of dose computation within the lungs depends strongly on the performance of
the calculation algorithm in regions of electronic disequilibrium that arise near tissue …

The geant4 Monte Carlo code provides many powerful functions for conducting particle
transport simulations with great reliability and flexibility. However, as a general purpose …

PURPOSE: Water equivalent path length (WEL) variations due to respiration can change the
range of a charged particle beam and result in beam overshoot to critical organs or beam …

To evaluate the dose values predicted by several calculation algorithms in two treatment
planning systems, Monte Carlo (MC) simulations and measurements by means of various …

The minimum margins required to compensate for random geometric uncertainties in the
delivery of radiotherapy treatment were determined for a spherical Clinical Target Volume …

In systemic radiation therapy, the absorbed dose distribution must be calculated from the
individual activity distribution. A computer code has been developed for the conversion of an …

Abstract The Monte Carlo (MC) method has long been viewed as the ultimate dose
distribution computational technique. The inherent stochastic dose fluctuations (ie noise) …
