Written at the technologist level, Nuclear Medicine Instrumentation, Second Edition focuses on instruments essential to the practice of nuclear medicine.Covering everything from Geiger counters to positron emission tomography systems, this text provides students with an understanding of the practical aspects of these instruments and their uses in nuclear medicine.Nuclear Medicine Instrumentation is made up of four parts: Small Instruments Gamma Camera Single Photon Emission Computed Tomography (SPECT) Positron Emission Tomography (PET)By concentrating on the operation of these instruments and the potential pitfalls that they are subject to, students will be better prepared for what they may encounter during their career.The Second Edition includes revised content and updated data throughout as well as a new chapter on Magnetic Resonance Imaging and Its Application to Nuclear Medicine and a new Appendix. What#146;s New in the Second Edition Content and Data updated and revised throughout. New: Chapter 19 Magnetic Resonance Imaging and Its Application to Nuclear Medicine. Chapter 2 -- includes a new concept map elucidating the operation of a scintillation detector, a better description of calibration, and clarification of energy resolution (the property being measured) vs. FWHM ( the mechanism by which it is measured). Chapter 5 -- the section on non-Anger cameras was rewritten to address planar devices only, with descriptions of non-Anger SPECT systems in Chapter 12. Chapter 8 -- the sections on background and noise have been rewritten. Chapter 10 -- the description of SPECT axes was changed to match that used for other types of tomographic imaging systems. Chapter 12 -- this chapter was updated to include recent improvements, a section on noise regularization, and more information on implementation and clinical benefits. Both software methods of incorporating improvements and non-Anger 3D imaging systems are discussed. Chapter 15 -- photos of a PET tomograph taken apart are included, so that the reader can see crystals, septa, electronics, and a rod source. The description of direct and cross-planes is expanded. There is decreased emphasis on 2D vs. 3D imaging, and new sections on dynamic and gated imaging and organ-specific PET systems are included. Chapter 16 -- the section on the SUV is rewritten to reflect its increasing importance, and a new section on the benefits of time-of-flight PET is included. Chapter 19 -- this is a completely new chapter on MRI, written as the first PET/MRI scanners are coming into clinical use. It aims to provide a modest rather than in-depth level of understanding of MRI as well as the technological challenges and clinical benefits of combining MRI with PET imaging. Appendix A -- extensively rewritten to emphasize the consequences of radiation interactions. Appendix F -- a new appendix on laboratory accreditation; references to the requirements of accrediting agencies are also sprinkled throughout the text as appropriate.
