Human EPR Dosimetry at Low Accumulated Dose of Ionizing Radiation Human EPR Dosimetry at Low Accumulated Dose of Ionizing Radiation
A new method for tooth (enamel and dentine) and bone EPR dosimetry is proposed that enhances substantially the dosimetric sensitivity. The method is based on the nonstandard spectra registration mode (the second harmonic phase quadrature detection of absorption under rapid passage conditions). This method provides an apparent enhancement of the component ratio of radiation to a nonradiative bac...
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...
متن کاملMeasurement of absorbed dose in normoxic polymer gel and study of gold nanoparticles configuration effects
Radiotherapy includes all methods that can deliver a particular amount of ionizing radiation to malignant tissues, assuming that minimal damage hurts healthy tissues. We are looking for a valuable and reliable method to measure absorbed dose and the ability to measure the distribution of absorbed dose in three dimensions which nowadays is one of the three-dimensional dosimetry methods in using ...
متن کاملOptical and NMR dose response of N-isopropylacrylamide normoxic polymer gel for radiation therapy dosimetry.
BACKGROUND Application of less toxic normoxic polymer gel of N-isopropyl acrylamide (NIPAM) for radiation therapy has been studied in recent years. AIM In the current study the optical and NMR properties of NIPAM were studied for radiation therapy dosimetry application. MATERIALS AND METHODS NIPAM normoxic polymer gel was prepared and irradiated by 9 MV photon beam of a medical linac. The o...
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...
