Available in PDF, EPUB and Kindle. Book excerpt: Expressions are developed which give the amount of unidirectional radiation from a distant radiation source passing through a cylindrical hole in a slab of material, including the amount of radiation which penetrates the edges of the hole, as a function of angle between the radiation direction and the axis of the hole. The modifications necessary for sources at finite distances are indicated. These functions are integrated over appropriate angles for distant line sources and for extended sources. It is shown that, to a first approximation, the results are the same as the geometrical aperture for a like diameter hole in a similar slab with one mean free path of material removed from each side. The effects due to scattering from the walls of the collimator are discussed and an approximate method of calculation is presented with results for a specific collimator.

This book was released on 1962 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The angular distribution of dose rate resulting from gamma rays of Co-60 and Cs-137 transmitted through various thicknesses of iron (0.737 in. and 1.6 in.) and aluminum (2 in., 4 in., and 9 in.) was measured. These experimental results are compared with Monte Carlo calculations. Comparisons over a limited range of these angular variables are also made with dose-rate distributions calculated from gamma-ray spectrometric data.

This book was released on 2013-11-11 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The material in this volume was prepared and collected over the past four years with the growing realization that a technical revolution was in progress for diagnostic medicine. It became clear that for the wide variety of imaging instruments and methods finding their way into applications for research and clinical medicine, there was a scarcity of reference and text books for the scientist and engineer beginning in the field. Thus what began as a relatively small project for a single volume has grown into certainly two and probably three volumes to adequately cover the field. This first volume is expected to be followed within a few months by a second volume, dealing with diagnostic radiology, and within a year by a third volume, covering most other aspects of medicine that utilize spectra from the ultraviolet through the visible into the near-infrared. The chapters in this book are divided into three groups. The first group deals with nuclear medicine and includes Chapters 1-8. These chapters are arranged to begin with a broad introduction to the subject (Chapter 1) followed by a sequence of four chapters (Chapters 2-5) that provide an in-depth review of the imaging instrumentation developed for the field. Chapter 6 deals with "evaluation" of imaging device per formance, while Chapters 7 and 8 discuss two areas of considerable re search activity.

Download or read book FRCR Physics Notes written by Christopher Clarke and published by . This book was released on 2020-11-13 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive medical imaging physics notes aimed at those sitting the first FRCR physics exam in the UK and covering the scope of the Royal College of Radiologists syllabus. Written by Radiologists, the notes are concise and clearly organised with 100's of beautiful diagrams to aid understanding. The notes cover all of radiology physics, including basic science, x-ray imaging, CT, ultrasound, MRI, molecular imaging, and radiation dosimetry, protection and legislation. Although aimed at UK radiology trainees, it is also suitable for international residents taking similar examinations, postgraduate medical physics students and radiographers. The notes provide an excellent overview for anyone interested in the physics of radiology or just refreshing their knowledge. This third edition includes updates to reflect new legislation and many new illustrations, added sections, and removal of content no longer relevent to the FRCR physics exam. This edition has gone through strict critique and evaluation by physicists and other specialists to provide an accurate, understandable and up-to-date resource. The book summarises and pulls together content from the FRCR Physics Notes at Radiology Cafe and delivers it as a paperback or eBook for you to keep and read anytime. There are 7 main chapters, which are further subdivided into 60 sub-chapters so topics are easy to find. There is a comprehensive appendix and index at the back of the book.

Download or read book Instrumentation in Nuclear Medicine written by Gerald J. Hine and published by Academic Press. This book was released on 2013-10-22 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instrumentation in Nuclear Medicine discusses both the fundamentals and the developments of important instruments used in nuclear medicine. Both theoretical and experimental aspects of the field are presented together, with specific information on its applications. The book is divided into four parts. Part I deals with the fundamental concepts such as radioisotopes and labeled compounds; the establishment and maintenance of a radioisotope laboratory; and basic considerations in nuclear instrumentation. Part II covers topics such as Geiger-Muller and proportional counters, semiconductor detectors, and other systems for data accumulation and presentation. Part III concerns itself with measurements of biological samples, preparation of samples for liquid scintillation counting and involved equipment, and radiochromatographic counting techniques. Part IV tackles radioisotope measurements in vivo such as thyroid radioiodine uptake measurements, single and multiple detector systems for whole-body counting, and large organic scintillation detectors. The text is recommended for medical technologists and radiologists who would like to know more about the fundamentals, applications, and advances in the instrumentation involved in nuclear medicine.
