Available in PDF, EPUB and Kindle. Book excerpt: "192Ir is one of the most popular radiation sources used for brachytherapy treatments. However, 192Ir emits a wide photon spectrum (10 keV to 900 keV) which impedes the creation of an 192Ir primary standard. The 192Ir air kerma calibration factor is derived by interpolating between 60Co, 137Cs and hard orthovoltage air kerma calibration factors obtained from a standards laboratory. The EGSnrc Monte Carlo package was used to calculate the response in low energy photon beams of a commercial parallel-plate chamber to assess useability as a 192Ir and kilovoltage photon beam calibration tool. XCOM photoeffect cross-sections were implemented in EGSnrc to improve kerma calculation agreement at low energies. The response calculations were compared to experimental data from PTB (Germany). Overall, agreement between calculations and measurement is good and represents an improvement to results from the literature. However, discrepancies exist at the lowest energies which may be caused by differences in the measurement and calculation geometries." --

Download or read book Tumor Response Monitoring and Treatment Planning written by A. Heuck and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medical imaging progressed to a standard undreamt of not very many years ago. The advances are due to continuous development of radiological techniques and the introduction of magnetic resonance imaging. With the improved and new methods three-dimensional target volumes for radiation therapy can be defined with hitherto unknown precision. This leads to an improvement in irradiation techniques and, as a consequence, to a higher likelihood of tumor control and a lower risk of normal tissue complications. Besides the improvement in irradiation techniques the new imaging methods may enable great strides in tumor response monitoring, not only in the detection of morphological alterations but also by showing physiological changes in the tumor during and after treatment by means of MRI and PET. This not only leads to better prognostic information but may also allow early evaluation of the response to treatment. It may then be possible to individualize the radiation dose but also the alternative-treatment for non-responders. This is certainly a future direction for radiation oncology.
Download or read book Introduction to Radiological Physics and Radiation Dosimetry written by Frank Herbert Attix and published by John Wiley & Sons. This book was released on 2008-09-26 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: A straightforward presentation of the broad concepts underlying radiological physics and radiation dosimetry for the graduate-level student. Covers photon and neutron attenuation, radiation and charged particle equilibrium, interactions of photons and charged particles with matter, radiotherapy dosimetry, as well as photographic, calorimetric, chemical, and thermoluminescence dosimetry. Includes many new derivations, such as Kramers X-ray spectrum, as well as topics that have not been thoroughly analyzed in other texts, such as broad-beam attenuation and geometrics, and the reciprocity theorem. Subjects are layed out in a logical sequence, making the topics easier for students to follow. Supplemented with numerous diagrams and tables.
Download or read book Basic Clinical Radiobiology written by Michael C. Joiner and published by CRC Press. This book was released on 2018-08-28 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic Clinical Radiobiology is a concise but comprehensive textbook setting out the essentials of the science and clinical application of radiobiology for those seeking accreditation in radiation oncology, clinical radiation physics, and radiation technology. Fully revised and updated to keep abreast of current developments in radiation biology and radiation oncology, this fifth edition continues to present in an interesting way the biological basis of radiation therapy, discussing the basic principles and significant developments that underlie the latest attempts to improve the radiotherapeutic management of cancer. This new edition is highly illustrated with attractive 2-colour presentation and now includes new chapters on stem cells, tissue response and the convergence of radiotherapy, radiobiology, and physics. It will be invaluable for FRCR (clinical oncology) and equivalent candidates, SpRs (and equivalent) in radiation oncology, practicing radiation oncologists and radiotherapists, as well as radiobiologists and radiotherapy physicists.

Download or read book Radiation Dosimetry written by C.G. Orton and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved in a sea of radiation. We have been bombarded constantly by X rays, y rays, UV rays, and particulate radiations from outer space, and by terrestrial radiations from the ground we walk on, from our building materials, and from our own bodies. Recently, we have become increasingly subjected to man-made radiations, especially from the medical and defense industries. All of these radiations are capable of affecting us biologically, both to our benefit and to our detriment. This book provides a thorough review of the physical and biological dosimetry of these radiations. It is targeted to those health professionals who are concerned with understanding the mechanisms fundamental to the biological action of ionizing radiation or who are involved in the application, measurement, or treatment of the effects of such radiations. The first chapter, on "Bioeffect Dosimetry in Radiation Therapy," should be of special interest to anyone involved in the treatment of cancer by radiation. It includes a brief review of the history of the manipulation of time-dose parameters in order to improve therapeutic benefit, and an up-to-date analysis of time-dose relationships designed for use in fractionated radiotherapy and brachytherapy. This is followed by two chapters reviewing and comparing national and international protocols for the precise measurement of photon and electron radiations in therapy. These chapters should be invaluable to radiation physicists responsible for treatment machine calibrations.

Available in PDF, EPUB and Kindle. Book excerpt: This publication provides guidelines on how to plan a radiotherapy facility in terms of the strategic master planning process including the legal, technical and infrastructure requirements. It outlines a risk assessment methodology and a typical project work plan, and describes the professional expertise required for the implementation of such a project. Generic templates for a block design are suggested, which include possibilities for future expansion. These templates can be overlaid onto the designated site such that the most efficient workflow between the main functional areas can be ensured. A sample checklist is attached to act as a guideline for project management and to indicate the critical stages in the process where technical expert assistance may be needed. The publication is aimed at professionals and administrators involved in infrastructure development, planning and facility management, as well as engineers, building contractors and radiotherapy professionals.
