Dosimetry in CR mammography using radiochromic film

Brazilian Journal of Radiation Sciences, 2022
To estimate the dose that a patient's mammary tissue receives during mammographic screening, radiochromic film and objects simulators made of PMMA are used. This material interacts with X-rays in a similar way to tissue. Estimating the dose absorbed by a

Comparison of established and emerging biodosimetry assays [PDF]

, 2013
Rapid biodosimetry tools are required to assist with triage in the case of a large-scale radiation incident. Here, we aimed to determine the dose-assessment accuracy of the well-established dicentric chromosome assay (DCA) and cytokinesis-block ...

Real-time dosimetry with radiochromic films [PDF]

Scientific Reports, 2019
AbstractRadiochromic film dosimetry has been widely employed in most of the applications of radiation physics for over twenty years. This is due to a number of appealing features of radiochromic films, such as reliability, accuracy, ease of use and cost. However, current radiochromic film reading techniques, based on the use of commercial densitometers

The combination of the error correction methods of GAFCHROMIC EBT3 film. [PDF]

PLoS ONE, 2017
The aim of this study was to combine a set of methods for use of radiochromic film dosimetry, including calibration, correction for lateral effects and a proposed triple-channel analysis. These methods can be applied to GAFCHROMIC EBT3 film dosimetry for

Reference dosimetry using radiochromic film

Journal of Applied Clinical Medical Physics, 2012
The objectives of this study are to identify and quantify factors that influence radiochromic film dose response and to determine whether such films are suitable for reference dosimetry. The influence of several parameters that may introduce systematic dose errors when performing reference dose measurements were investigated.
