Download or read book Absorbed Dose to Water Calibration of Ionization Chambers in a 60co Gamma ray Beam written by nist and published by Createspace Independent Publishing Platform. This book was released on 2013-12-11 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Absorbed-dose-to-water calibrations are important to the medical community to facilitate the accurate determination of doses delivered to tumors during external-beam cancer therapy. The first version of this document offered an absorbed-dose-to-water calibration service based on a graphite calorimeter as the primary standard. However, the use of this calorimeter necessitated calculations to convert the measurement from graphite to water. In 1989, a water calorimeter was introduced at the National Institute of Standards and Technology (NIST), which was to replace the graphite calorimeter as the primary standard. Though the calculations necessary for conversion factors were eliminated with this new technology, a calibration service based on the water calorimeter was not developed at this time. Despite the fact that the service was available, the medical physics community did not take advantage of it and used chambers calibrated in terms of exposure (in units of roentgen) to calibrate their radiotherapy 60Co and high-energy electron accelerator x-ray. A protocol, commonly known as TG21, developed by the American Association of Physicists in Medicine (AAPM), involves many calculations to arrive at the quantity desired by the medical physicist in the practicing clinic, cGy/MU (centiGray/monitor unit). The AAPM has initiated a new protocol through Task Group 51 which involves absorbed-dose-to-water calibrations of ion chambers commonly used in the calibration of the clinical radiotherapy photon and electron beams.NIST has developed and is now prepared to offer the absorbed-dose-towater calibration service for ionization chambers based on a water calorimeter standard developed by Steve Domen at NIST. This document outlines the steps that have been taken to develop this service including a brief description of the Domen water calorimeter. The procedures that are involved in the calibration of an ionization chamber for this quantity are presented along with results from recent comparisons of the NIST with the Bureau International des Poids et Mesures (BIPM) in France and the National Radiation Council Canada (NRCC).

Download or read book Absorbed Dose Determination in Photon and Electron Beams written by International Atomic Energy Agency and published by . This book was released on 1997 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition contains eight additional pages, summarizing recommended changes resulting from a review of data and procedures presented in the first edition. Otherwise, the report remains unchanged. The report itself represents a step towards a universal code advising users in Secondary Standard Dosimetry Laboratories (SSDLs) and radiation therapy centres throughout the world on how to obtain the absorbed dose from a measurement of exposure or another appropriate quantity. As the numerical result of a physical measurement must be complemented by an assessment of its uncertainty, Appendix A to this Code gives a brief summary of a treatment uncertainties concept by A. Allisy and J.W. Müller from the Bureau International des Poids et Mesures (BIPM).

Download or read book Accuracy Requirements and Uncertainties in Radiotherapy written by International Atomic Energy Agency and published by . This book was released on 2017-04-12 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accuracy requirements in radiation oncology have been defined in multiple publications; however, these have been based on differing radiation technologies. In the meantime, the uncertainties in radiation dosimetry reference standards have been reduced and more detailed patient outcome data are available. No comprehensive literature on accuracy and uncertainties in radiotherapy has been published so far. The IAEA has therefore developed a new international consensus document on accuracy requirements and uncertainties in radiation therapy, to promote safer and more effective patient treatments. This publication addresses accuracy and uncertainty issues related to the vast majority of radiotherapy departments including both external beam radiotherapy and brachytherapy. It covers clinical, radiobiological, dosimetric, technical and physical aspects.
