This third edition of The Physics of Medical Imaging provides completely new and comprehensive descriptions of the physical principles and concepts which underpin all the medical imaging technologies found in modern hospitals, including x-ray imaging, magnetic resonance imaging, nuclear medicine imaging, and ultrasound. In addition, this edition describes a range of new imaging techniques whose clinical impact is beginning to emerge or broaden significantly. With the aid of numerous illustrations, descriptions cover the basic mathematical principles, the design and operation of the imaging technology, and a review of the clinical applications. The criteria which determine imaging system performance are described, with an examination of the advantages and limitations of each modality, and the image artefacts to which each is prone. Additional chapters cover the basic principles of image formation, digital image processing methods, and image registration.Key Features:This thoroughly updated and modernised edition includes descriptions of many new innovations such as ultrasound tomography, susceptibility contrast MRI, and multimodality imaging (e.g. SPECT-CT), and new chapters on emerging imaging modalities such as optical coherence tomography, phase contrast x-ray imaging, and photoacoustic imagingContributors are leading scientists, engineers, and clinicians working on cutting edge research in medical imagingThe conceptual and mathematical descriptions of the imaging methods are accompanied by over 250 new diagrams and imagesContributors have extensive experience of teaching medical imaging physics, ensuring that the content is strongly informed by students' learning experiences, and by an appreciation of the intellectual challenges confronting students encountering new concepts in medical imagingThis book has been designed to be accessible to readers with a basic physics knowledge wishing to learn about medical imaging for the first time, or to deepen their understanding of diagnostic imaging techniques. This includes undergraduates in physics and engineering, research students, scientists, and healthcare professionals with interests in imaging
