Three-dimensional radiation dosimetry using polymer gel and solid radiochromic polymer: From basics to clinical applications
Accurate dose measurement tools are needed to evaluate the radiation dose delivered to patients by using modern and sophisticated radiation therapy techniques. However, the adequate tools which enable us to directly measure the dose distributions in three-dimensional (3D) space are not commonly available. One such 3D dose measurement device is the polymer-based dosimeter, which changes the mate...
متن کاملThree dimensional radiation dosimetry using polymer gels
The use of polymer gels to record radiation dose distributions in three dimensions was first proposed in 1992 as a proof-of-principle [1]. The accuracy of these early polymer gel dosimeters and scanning methods was not sufficient for most clinical applications [2]. Since then, several efforts were made to increase the accuracy and precision of both the physical gel dosimeter and the scanning te...
متن کاملEvaluation of radiochromic gel dosimetry and polymer gel dosimetry in a clinical dose verification.
A quantitative comparison of two full three-dimensional (3D) gel dosimetry techniques was assessed in a clinical setting: radiochromic gel dosimetry with an in-house developed optical laser CT scanner and polymer gel dosimetry with magnetic resonance imaging (MRI). To benchmark both gel dosimeters, they were exposed to a 6 MV photon beam and the depth dose was compared against a diamond detecto...
متن کاملRadiation dosimetry using polymer gels: methods and applications.
New, complex radiotherapy delivery techniques require dosimeters that are able to measure complex three-dimensional dose distributions accurately and with good spatial resolution. Polymer gel is an emerging new dosimeter being applied to these challenges. The aim of this review is to present a practical overview of polymer gel dosimetry, including gel manufacture, imaging, calibration and appli...
متن کاملVerification of MRI MAGAT polymer gel dosimetry in clinical radiotherapy applications
Introduction: The objective of this work is to study the ability of MRI normoxic polymer gel dosimetry system to be used to verify the calculated dose distribution, in a simple geometry, in clinical radiotherapy. Materials and Methods: Initially, 2 liters of the normoxic MAGAT polymer gel was prepared and then poured into two cylindrical Perspex phantom (simu...
