Brachytherapy polymer gel dosimetry with xCT
ABSTRACTBackground: Polymer gels are an emerging new class of dosimeters which are being applied to the challenges of modern radiotherapy modalities. Research on gel dosimetry involves several scientific domains, one of which is the imaging techniques with which dose data is extracted from the dosimeters. In the current work, we present our preliminary results of investigating capability of X-r...
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 کاملUncertainty Analysis in MRI-based Polymer Gel Dosimetry
Background: Polymer gel dosimeters combined with magnetic resonance imaging (MRI) can be used for dose verification of advanced radiation therapy techniques. However, the uncertainty of dose map measured by gel dosimeter should be known. The purpose of this study is to investigate the uncertainty related to calibration curve and MRI protocol for MAGIC (Methacrylic and Ascorbic acid in Gelatin I...

متن کاملMagnetic Resonance Elastography of Polymer Gel Dosimetry Phantoms
Introduction: Magnetic resonance imaging dependent polymer gel dosimetry is a technique that offers unique advantages for implementing increasingly complex radiotherapy procedures, due to the high spatial resolution and volumetric dosimetry capabilities. The technique involves the estimation of radiation dose distribution based on the changes in MR relaxation parameters caused by radiation indu...
