Skin dose investigations on a 0.5 T parallel rotating biplanar linac‐MR using Monte Carlo simulations and measurements

Medical Physics, Volume 51, Issue 9, Page 6317-6331, September 2024.
Abstract Background The Alberta rotating biplanar linac‐MR has a 0.5 T magnetic field parallel to the beamline. When developing a new linac‐MR system, interactions of charged particles with the magnetic field necessitate careful consideration of skin dose and tissue interface effects. Purpose To investigate the effect of the magnetic field on skin dose

Dosimetry effects caused by unilateral and bilateral hip prostheses: A monte carlo case study in megavoltage photon radiotherapy for computed tomography data without metal artifacts

Journal of Medical Physics, 2018
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:
