Technical innovation changes standard radiographic protocols in veterinary medicine: is it necessary to obtain two dorsoproximal-palmarodistal oblique views of the equine foot when using computerised radiography systems? [PDF]

open access: yes, 2016
Since the 1950s, veterinary practitioners have included two separate dorsoproximal–palmarodistal oblique (DPr–PaDiO) radiographs as part of a standard series of the equine foot.

Dosimetric evidence confirms computational model for magnetic field induced dose distortions of therapeutic proton beams

open access: yes, 2017
Given the sensitivity of proton therapy to anatomical variations, this cancer treatment modality is expected to benefit greatly from integration with magnetic resonance (MR) imaging.

Overview of the sensitivity of Ge- and Al-doped silicon dioxide optical fibres to ionizing radiation [PDF]

open access: yes, 2012
This paper reviews the thermoluminescence sensitivity of Ge- and Al- doped SiO2 optical fibre subjected to various ionizing radiations. It is found that the Ge- doped SiO2 optical fiber has the thermoluminescence response superior to Al-doped SiO2 ...

Model selection for radiochromic film dosimetry [PDF]

open access: yesPhysics in Medicine and Biology, 2015
The purpose of this study was to find the most accurate model for radiochromic film dosimetry by comparing different channel independent perturbation models. A model selection approach based on (algorithmic) information theory was followed, and the results were validated using gamma-index analysis on a set of benchmark test cases.

Development and operation of a pixel segmented liquid-filled linear array for radiotherapy quality assurance

open access: yes, 2004
A liquid isooctane (C$_{8}$H$_{18}$) filled ionization linear array for radiotherapy quality assurance has been designed, built and tested. The detector consists of 128 pixels, each of them with an area of 1.7 mm $\times$ 1.7 mm and a gap of 0.5 mm.

Applicator Attenuation Effect on Dose Calculations of Esophageal High-Dose Rate Brachytherapy Using EDR2 Film [PDF]

open access: yesIranian Journal of Medical Physics, 2012
Introduction Interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. The effect of applicator attenuation is not considered in dose calculation method released by AAPM-TG43. In this study, the effect of High-Dose Rate (

Application of a Portable Colorimeter for Reading a Radiochromic Film for On-Site Dosimetry

open access: yesApplied Sciences, 2023
Radiochromic films have widely been used for quality assurance (QA) in radiation therapy and have many advantageous features such as self-developing visible coloration, wide dose range and easiness to handle.

Companding technique for high dynamic range measurements using gafchromic films

open access: yes, 2011
We propose a methodology to perform dose measurements using gafchromic films which can span several decades of dose levels. The technique is based on a rescaling approach using different films irradiated at different dose levels.
