Journal ArticleDOI
Analysis of small field percent depth dose and profiles: Comparison of measurements with various detectors and effects of detector orientation with different jaw settings.
TL;DR: Among all detectors used in the study, the unshielded diodes were found to be an appropriate choice of detector for the measurement of beam parameters in small fields.
Journal ArticleDOI
Dosimetric verification of brain and head and neck intensity-modulated radiation therapy treatment using EDR2 films and 2D ion chamber array matrix
TL;DR: Due to simplicity and fast evaluation process of array detectors, it can be routinely used in busy departments without compromising the measurement accuracy.
Journal ArticleDOI
Implementation and validation of a commercial portal dosimetry software for intensity-modulated radiation therapy pre-treatment verification.
TL;DR: The newly developed portal dosimetry software using independent dose prediction algorithm EPIDose™ is implemented and this new tool for the pre-treatment IMRT plan quality assurance of Whole Pelvis with Simultaneous Integrated Boost (WP-SIB-IMRT) of prostate cases is evaluated by comparing with routine two-dimensional array detector system (MapCHECK™).

TL;DR: The aim of this study was to optimize dose distribution for Gammamed plus vaginal cylinders and found that the effect of source travel step size on the optimized dose distributions for vaginal cylinders was also evaluated.
Journal ArticleDOI
Variation of beam characteristics between three different wedges from a dual-energy accelerator.
TL;DR: The purpose of this study was to compare the dosimetric characteristics of a physical and enhanced dynamic wedge from a dual-energy (6 and 18 MV) linear accelerator such as surfaces doses with different source to surface distances (SSD), half value layer (HVL) in water and peripheral doses for both available energies.
