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.

Book excerpt: The need in clinical nuclear medicine for imaging devices with high spatial resolution has been discussed at length for many years. More recently, specialists in cardiology and neurology have restated this need for greater resolution in order to effect earlier or more accurate diagnoses of brain tumors, cerebral and myocardial ischemia and infarcts and septum defects, among others. Our approach to filling this need is to ultimately develop a 3072-element, high-purity germanium camera with a 2-mm spatial resolution, an energy resolution of 2 to 3 percent for /sup 99m/Tc, and a clinically useful area of 123 cm2 for imaging the average adult heart, breast or brain. To this end, a 100-element prototype has been constructed and images of rats and mice have been obtained with the use of single and multiple isotopes. A second prototype with 512 elements has also been completed and tested. The 512 elements are derived from an array of electrodes, on the bottom of two germanium crystals, orthogonal to 16 electrodes on the top. The top electrodes are electrically in parallel and have a common electronic readout. The p-contact is palladium over germanium oxide, and the n-side is gold over the lithium diffusion. Cooling for the detector is accomplished through a sapphire motherboard by way of indium contacts which are also the electrical contacts for the n-side. The isolation between the strips on the p- and the n-sides is adequate to attain good energy resolution.

Book excerpt: We report on the first experimental demonstration of Compton imaging of gamma rays with a single coaxial high-purity germanium (HPGe) detector. This imaging capability is realized by two-dimensional segmentation of the outside contact in combination with digital pulse-shape analysis, which enables to image gamma rays in 4[pi] without employing a collimator. We are able to demonstrate the ability to image the 662keV gamma ray from a 137Cs source with preliminary event selection with an angular accuracy of 5 degree with an relative efficiency of 0.2%. In addition to the 4[pi] imaging capability, such a system is characterized by its excellent energy resolution and can be implemented in any size possible for Ge detectors to achieve high efficiency.

This book was released on 2018-06-27 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complexity and vulnerability of the human body has driven the development of a diverse range of diagnostic and therapeutic techniques in modern medicine. The Nuclear Medicine procedures of Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT) and Radionuclide Therapy are well-established in clinical practice and are founded upon the principles of radiation physics. This book will offer an insight into the physics of nuclear medicine by explaining the principles of radioactivity, how radionuclides are produced and administered as radiopharmaceuticals to the body and how radiation can be detected and used to produce images for diagnosis. The treatment of diseases such as thyroid cancer, hyperthyroidism and lymphoma by radionuclide therapy will also be explored.

Download or read book Gamma Cameras for Interventional and Intraoperative Imaging written by Alan C. Perkins and published by CRC Press. This book was released on 2016-11-03 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamma cameras are traditionally large devices that are situated in nuclear medicine departments, but recent advances in detector design have enabled the production of compact gamma cameras that allow nuclear imaging at the patient bedside and in the operating theatre. Gamma Cameras for Interventional and Intraoperative Imaging is the first book to cover this new area of imaging, and provides a unique insight into the experimental and clinical use of small field of view gamma cameras in hospitals. This book explores advances in the design and operation of compact gamma cameras and conducts a thorough review of current SFOV systems, before exploring the clinical applications of the technology. It is an essential reference for surgeons, operating theatre staff, clinical scientists (medical physicists), technologists, nuclear physicians and radiologists whose patients could benefit from this technology.

Download or read book Germanium Based Detectors for Gamma Ray Imaging AndSpectroscopy written by and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Germanium-based detectors are the standard technology usedfor gamma-ray spectroscopy when high efficiency and excellent energyresolution are desired. By dividing the electrical contacts on thesedetectors into segments, the locations of the gamma-ray interactionevents within the detectors can be determined as well as the depositedenergies. This enables simultaneous gamma-ray imaging and spectroscopyand leads to applications in the areas of astronomy, nuclear physics, environmental remediation, nuclear nonproliferation, and homelandsecurity. Producing the fine-pitched electrode segmentation oftenrequired for imaging has been problematic in the past. To address thisissue, we have developed an amorphous-semiconductor contact technology. Using this technology, fully passivated detectors with closely spacedcontacts can be produced using a simple fabrication process. The currentstate of the amorphous-semiconductor contact technology and thechallenges that remain will be given in this paper.
