1. Characterization and Clinical Application of Normoxic Polymer Gel in Radiation Therapy Dosimetry
Abstract : Cancer is one of the main causes of death in the world, particularly in developing countries and is considered as a major public health problem. Radiation therapy has been an important modality for treatment of cancer for many decades. READ MORE

2. Implementation of MRI gel dosimetry in radiation therapy
Abstract : Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. READ MORE

3. Radiotherapy Gel Dosimetry: Development and Application of Normoxic Polymer Gels
Abstract : In many radiotherapy applications, true three-dimensional dosimetry with good spatial resolution that can be achieved in a single measurement would be of great value. Polymer gel dosimetry fulfils many of the demands on such a system. In this study, methods to facilitate the implementation of gel dosimetry have been investigated. READ MORE

4. Quality Assurance in Radiotherapy - Development and evaluation of new tools for improved patient safety
Abstract : Preparation for radiotherapy is a complex procedure that involves many different technologies and groups of professionals. The rapid development and introduction of new technologies throughout the last decade have made it possible to deliver highly conformal, individually-shaped dose distributions with high accuracy.

5. 3D Verification of Dynamic and Breathing Adapted Radiotherapy using Polymer Gel Dosimetry
Abstract : Polymer gel dosimetry has been used since the 1990s, and several studies have shown that this detector system can be used for verification of static absorbed dose distributions in three dimensions (3D). Its unique properties, such as high resolution, normal tissue equivalence and independency of energy, field size and direction of the incident radiation, should also be advantageous for dosimetric verification of radiotherapy using today’s and tomorrow’s dynamic delivery techniques.
