Dosimetric evaluation of GAFCHROMIC® XR type T and XR type R films
The high spatial resolution of radiochromic film makes it ideal for dosimetric measurements and dose distributions in regions of high dose gradient. Intensity-modulated radiation therapy, intravascular brachytherapy, and eye-plaque radiation therapy demand precise spatial dosimetric calculations. Such precision is not possible with conventional dosimeters, such as thermoluminescent dosimeters a...
متن کاملUltraviolet exposure of Gafchromic XR‐RV3 and XR‐SP2 films
Gafchromic film has been used for X-ray dose measurement in diagnostic examinations. Their use has been initiated for three-dimensional X-ray dose measurement by using the high-resolution characteristics of Gafchromic films in computed tomography. However, it is necessary to solve the problem of nonuniform thickness in the active layers of Gafchromic films. A double exposure technique using X-r...
متن کاملReflection spectrometry analysis of irradiated GAFCHROMIC XR type R radiochromic films.
The absorption spectra of the GAFCHROMIC XR type R radiochromic film measured with reflectance spectroscopy have been investigated in order to analyze the dosimetry characteristics of the film. Like the XR type T film, this film features two peaks in its absorption spectrum, approximately at 676 and 618 nm, whose intensities increase with increasing absorbed dose. When the main absorption peak ...
متن کاملMeasurement of dose‐area product with GafChromic XR Type R film
Many of the newer X-ray machines are equipped with electronic means to provide dose-area product (DAP) information. For machines without that ability, an alternative method is to record radiation on a film that can handle a large amount of cumulative exposure. The use of GafChromic XR Type R film was investigated for this purpose by placing it at the X-ray tube assembly to record the radiation ...
متن کاملDetermining rectal dose through cervix cancer radiotherapy by 9 MV photon beam using TLD and XR type T GAFCHROMIC® Film
Background: The goals of the present research were to investigate the rectal dose during four chosen techniques of cervical cancer radiotherapy and to examine how accurately the treatment planning represents dose measurements, and it’s practicality for routine use as well as, to determine the homogeneity of dose in tumor volume. Materials and Methods: The study was carried out using a Nepton 10...
