Background: Hip prostheses (HPs) are routinely used in hip augmentation to replace painful or dysfunctional hip joints. However, high-density and high-atomic-number (Z) inserts may cause dose perturbations in the target volume and interface regions. Aim:

COMET-PE as an Alternative to Monte Carlo for Photon and Electron Transport
Monte Carlo methods are a central component of radiotherapy treatment planning, shielding design, detector modeling, and other applications. Long calculation times, however, can limit the usefulness of these purely stochastic methods.

Abstract Background Magnetic resonance (MR) imaging devices have been integrated with medical linear accelerators (linac) in radiation therapy. Both perpendicular linac‐MR (LMR‐B⊥) and parallel (LMR‐B∥) systems exist, where due to the MR's magnetic field dose can be perturbed in the patient.

Minimum phantom size for megavoltage photon beam reference dosimetry
Abstract Background Water phantoms are required to perform reference dosimetry and beam quality measurements but there are no published studies about the size requirements for such phantoms. Purpose To investigate, using Monte Carlo techniques, the size requirements for water phantoms used in reference dosimetry and/or to measure the beam quality ...
