Download or read book The New ICRU Report On Prescribing Recording And Reporting Light Ion Beam Therapy written by Tadashi Kamada and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An ICRU report on Prescribing, Recording and Reporting Light Ion Beam Therapy has been submitted to the Journal of the ICRU by end of 2018. This report is the result of a longstanding collaboration between the IAEA and ICRU and has been initiated after joint meetings in Vienna, Austria (2004) and Columbus, Ohio (2006) in an attempt to standardize the reporting of light ion beam radiotherapy. It relies on concepts previously developed by the ICRU for reporting other therapies but with special emphasis on the use and reporting of RBE-weighted quantities. Such harmonization will facilitate the comparison of therapeutic results obtained with ions not only between ion beam therapy centers but also with centers using other modern forms of radiation therapy, such as proton-RT and IMRT with photon beams. The report outlines the different biological models used for calculating RBE weighted dose for light ion beam therapy and attempts to clarify their clinical use in order to enable a common understanding of clinical practice in various facilities. It gives detailed recommendations on how light ion beam therapy should be prescribed, recorded and reported. The physical and technical background of light ion beam therapy is explained. The recommendations on dosimetry were harmonized and updated according to ICRU report 90 (Key Data for Ionizing-Radiation Dosimetry: Measurement Standards and Applications, 2016) and with the upcoming revision of IAEAu2019s TRS-398 (Absorbed Dose Determination in External Beam Radiotherapy: An International Code of Practice for Dosimetry based on Standards of Absorbed Dose to Water, 2016).

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 Dosimetry of Small Static Fields Used in External Beam Radiotherapy written by International Atomic Energy Agency and published by . This book was released on 2018-01-31 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first international code of practice dedicated to the dosimetry of small static fields used in radiotherapy. It provides consistent reference dosimetry, traceable to metrological primary standards, and enables common procedures within a country to be followed for small field dosimetry. The publication presents an overview of the physics, followed by a general formalism for reference dosimetry in small fields. Guidelines for its practical implementation using suitable detectors and methods for the determination of field output factors are given for specific clinical machines that use small static fields. The development of this code of practice has been done through an international working group, established jointly with the American Association of Physicists in Medicine. Internationally harmonized guidelines in this field will ensure worldwide consistency in dose delivery to radiotherapy patients and will contribute to dose standardization in international clinical trial studies, comparing outcomes of various radiotherapy treatment modalities using small fields.

Download or read book Airport Passenger Screening Using Backscatter X Ray Machines written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-01-10 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Passenger screening at commercial airports in the United States has gone through significant changes since the events of September 11, 2001. In response to increased concern over terrorist attacks on aircrafts, the Transportation Security Administration (TSA) has deployed security systems of advanced imaging technology (AIT) to screen passengers at airports. To date (December 2014), TSA has deployed AITs in U.S. airports of two different technologies that use different types of radiation to detect threats: millimeter wave and X-ray backscatter AIT systems. X-ray backscatter AITs were deployed in U.S. airports in 2008 and subsequently removed from all airports by June 2013 due to privacy concerns. TSA is looking to deploy a second-generation X-ray backscatter AIT equipped with privacy software to eliminate production of an image of the person being screened in order to alleviate these concerns. This report reviews previous studies as well as current processes used by the Department of Homeland Security and equipment manufacturers to estimate radiation exposures resulting from backscatter X-ray advanced imaging technology system use in screening air travelers. Airport Passenger Screening Using Backscatter X-Ray Machines examines whether exposures comply with applicable health and safety standards for public and occupational exposures to ionizing radiation and whether system design, operating procedures, and maintenance procedures are appropriate to prevent over exposures of travelers and operators to ionizing radiation. This study aims to address concerns about exposure to radiation from X-ray backscatter AITs raised by Congress, individuals within the scientific community, and others.
