Spatial resolution of a stacked radiochromic film dosimeter
Radiotherapy and Oncology, 2001The spatial resolution of stacked radiochromic film dosimeters, which have increased sensitivity from a single layer radiochromic film detector, has been studied.A 5-layer film which can easily be constructed provided a 4.3-times increase in sensitivity over a single layer film at 670 nm readout wavelength which meant that doses as low as 0.6 Gy could ...

Assessment of concomitant testicular dose with radiochromic film
Australasian Physical & Engineering Sciences in Medicine, 2013To assess the suitability of EBT2 and XRQA2 Gafchromic film for measuring low doses in the periphery of treatment fields, and to measure the accumulative concomitant dose to the contralateral testis resulting from CT imaging, pre-treatment imaging (CBCT) and seminoma radiotherapy with and without gonadal shielding.

A universal dose–response curve for radiochromic films
Medical Physics, 2015Purpose:This paper presents a model for dose–response curves of radiochromic films. It is based on a modified version of single‐hit model to take into account the growth experienced by lithium salt of pentacosa‐10,12‐diynoic acid polymers after irradiation.Methods:Polymer growth in radiochromic films is a critical phenomenon that can be properly ...

Characteristics of Gafchromic® XR‐RV2 radiochromic film
Medical Physics, 2009Gafchromic® XR‐RV2 is a revised version of the obsolete Gafchromic® XR‐R‐type radiochromic film. This article investigates the dose response, energy response, postexposure growth, and polarizing effects of this film after exposure to ionizing radiation in the diagnostic energy range. The effect of bit depth on scanning was also investigated. Films were

A prototype quantitative film scanner for radiochromic film dosimetry.
Medical physics, 2008We have developed a high resolution, quantitative, two-dimensional optical film scanner for use with a commercial high sensitivity radiochromic film (RCF) for measuring single fraction external-beam radiotherapy dose distributions. The film scanner was designed to eliminate artifacts commonly observed in RCF dosimetry. The scanner employed a stationary
