Investigation of the Spatial Resolution of MR-Based Polymer Gel Dosimetry versus Film Densitometry using Dose Modulation Transfer Function [PDF]
Iranian Journal of Medical Physics, 2011 Introduction: The conventional methods of dosimetry are not capable of dosimetry in such a small volume of less than one cubic millimeter. Although the polymer gel dosimetry method based on magnetic resonance imaging (MRI) could achieve three dimensional

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 Multigaussian method: a new approach to mitigating spatial heterogeneities with multichannel radiochromic film dosimetry [PDF]
Physics in Medicine and Biology, 2018 The main objective of multichannel radiochromic film dosimetry methods is to correct, or at least mitigate, spatial heterogeneities in the film-scanner response, especially variations in the active layer thickness.
