Summary:

The importance of medical imaging for diagnostics is strongly increasing. It is now necessary to have a good knowledge of the different physical principles possible. This book provides an overview of the progress made in the different domains of imaging from various angles. It describes the principles and types of equipment used in medical imaging. Chapter 1 focuses on medical ultrasound imaging, exploring the physical principles of ultrasound waves and the key performances of ultrasound systems used for medical diagnosis. A significant part of the chapter presents recent innovations in response to the challenges of imaging within the human body in real time. Chapter 2 is concerned with magnetic resonance imaging (MRI). It presents the fundamentals of MRI, its instrumentation in a hospital setting, an analysis of image properties, imaging sequences and modes of reconstruction, and finally, the applications of MRI, its uses and its evolution in the biomedical field. This book offers a rare global approach to the subject of medical imaging to all scientists and engineers working in hospitals or in the medical imaging industry. Book jacket.
