Practical and clinical considerations in Cobalt-60 tomotherapy

open access: yesJournal of Medical Physics, 2009
Cobalt-60 (Co-60) based radiation therapy continues to play a significant role in not only developing countries, where access to radiation therapy is extremely limited, but also in industrialized countries.

Monte Carlo Study of Fetal Dosimetry Parameters for 6 MV Photon Beam

open access: yesJournal of Medical Signals and Sensors, 2013
Because of the adverse effects of ionizing radiation on fetuses, prior to radiotherapy of pregnant patients, fetal dose should be estimated. Fetal dose has been studied by several authors in different depths in phantoms with various abdomen thicknesses ...

Technical note: Modeling a complex micro-multileaf collimator using the standard BEAMnrc distribution

open access: yes, 2010
Purpose: The component modules in the standard BEAMnrc distribution may appear to be insufficient to model micro-multileaf collimators that have trifaceted leaf ends and complex leaf profiles. This note indicates, however, that accurate Monte Carlo simulations of radiotherapy beams defined by a complex collimation device can be completed using BEAMnrc ...

Enhancement of the Dose on 12 MV Linac with Free Flattening Filter Mode

open access: yesJournal of Biomedical Physics and Engineering, 2019
Purpose: In the last years, some studies investigated dosimetric benefits of a free flattening filter for the photon mode in the radiotherapy field. This study aims to provide a theoretical study published and analysis of basic dosimetric properties ...
