Purpose: Accurate organs at risk definition is essential for radiation treatment of brain tumors. The aim of this study is to provide a stepwise and simplified contouring guide to delineate the OARs in the brain as it would be done in the everyday practice of planning radiotherapy for brain cancer treatment.
Methods: Anatomical descriptions and neuroimaging atlases of the brain were studied. The dosimetric
constraints used in literature were reviewed.
Results: A Computed Tomography and Magnetic Resonance Imaging based detailed atlas was developed jointly by radiation oncologists, a neuroradiologist and a neurosurgeon. For each organ brief anatomical notion, main radiological reference points and useful considerations are provided.
Recommended dose-constraints both for adult and pediatric patients were also provided.
Conclusions: This report provides guidelines for OARs delineation and their dose-constraints for the treatment planning of patients with brain tumors.

Geant4 Simulation of a filtered X-ray Source for Radiation Damage Studies

Geant4 low energy extensions have been used to simulate the X-ray spectra of industrial X-ray tubes
with filters for removing the uncertain low energy part of the spectrum in a controlled way. The results
are compared with precisely measured X-ray spectra using a silicon drift detector. Furthermore, this
paper shows how the different dose rates in silicon and silicon dioxide layers of an electronic device can
be deduced from the simulations.

کتاب Computing Radiation Dosimetry  CRD زبان اصلی 

Establishing reliable computational methods and tools for radiation dosimetry is of great importance today because of the increased use of radiation in a number of areas of science, technology and medical applications. Fields concerned include radiation protection, radiation shielding, radiation diagnostics and therapy, radiobiology, biophysics and radiation detection. This series of lectures delivered by experts provides the content of these workshop proceedings. They are a valuable reference for those wishing to better understand the most advanced computational methods in radiation dosimetry.
