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

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 …

Advances in radiotherapy technology during the last 25 years have significantly improved
both dose conformation to tumors and the preservation of healthy tissues, achieving almost …

Investigation of the normoxic PAGAT polymer gel dosimeter has been undertaken. The
concentrations of the chemical components of the gel were varied and its response to …

PURPOSE: In rectal cancer, combined radiotherapy and chemotherapy, either pre-or
postoperatively, is an accepted treatment. Late small bowel (SB) toxicity is a feared side …

A primary limitation of current x-ray CT polymer gel dosimetry is the low contrast, and hence
poor dose resolution, of dose images produced by the system. The low contrast is largely …

Of the antioxidants used to scavenge oxygen in polymer gel dosimeters, tetrakis
(hydroxymethyl) phosphonium chloride (THPC) has been shown to hold great promise due …

Gel dosimetry is the most promising 3D dosimetry technique in current radiation therapy
practice. X-ray CT has been shown to be a feasible method of reading out polymer gel …

This study reports new N-isopropylacrylamide (NIPAM) polymer gel recipes with increased
dose sensitivity and improved dose resolution for x-ray CT readout. NIPAM can be used to …

This article reports on the dosimetric properties of a new N-isopropylacrylamide, high% T,
polymer gel formulation (19.5% T, 23% C), optimized for x-ray computed tomography (CT) …
