Gel dosimetry was developed in the 1990s in response to a growing need for methods to
validate the radiation dose distribution delivered to cancer patients receiving high-precision …

Polymer gel dosimeters are fabricated from radiation sensitive chemicals which, upon
irradiation, polymerize as a function of the absorbed radiation dose. These gel dosimeters …

One of the challenges in PET/MRI is the derivation of an attenuation map to correct the PET
image for attenuation. Different methods have been suggested for deriving the attenuation …

Polymer gel dosimeters offer a wide range of potential applications in the three-dimensional
verification of complex dose distribution such as in intensity-modulated radiotherapy (IMRT) …

In polymer gel dosimetry using magnetic resonance imaging, the uncertainty in absorbed
dose is dependent on the experimental determination of T 2. The concept of dose resolution …

The aim of this work is to investigate the temporal stability of a polyacrylamide gelatin
hydrogel used for 3D monomer/polymer gel dosimetry techniques involving different …

For a physical measurement instrument different requirements have to be fulfilled such as its
insensitivity to uncontrollable environmental parameters and its stability. On the other hand …

In this study the stability of different polymer gel dosimeters is investigated. Further to a
previous chemical stability study on a (6% T, 50% C) PAG gel, the change in slope and …

Modern radiotherapy delivers highly conformal dose distributions to irregularly shaped
target volumes while sparing the surrounding normal tissue. Due to the complex planning …

The overall performance of polymer gel dosimeters for three-dimensional radiation
dosimetry is determined by the temporal and spatial stability of the gels, dose sensitivity and …
