Principles of Medical Imaging for Engineers introduces fundamental concepts related to why we image and what we are seeking to achieve to get good images, such as the meaning of ‘contrast’ in the context of medical imaging. This introductory text separates the principles by which ‘signals’ are generated and the subsequent ‘reconstruction’ processes, to help illustrate that these are separate concepts and also highlight areas in which apparently different medical imaging methods share common theoretical principles. Exercises are provided in every chapter, so the student reader can test their knowledge and check against worked solutions and examples. The text considers firstly the underlying physical principles by which information about tissues within the body can be extracted in the form of signals, considering the major principles used: transmission, reflection, emission and resonance. Then, it goes on to explain how these signals can be converted into images, i.e., full 3D volumes, where appropriate showing how common methods of ‘reconstruction’ are shared by some imaging methods despite relying on different physics to generate the ‘signals’. Finally, it examines how medical imaging can be used to generate more than just pictures, but genuine quantitative measurements, and increasingly measurements of physiological processes, at every point within the 3D volume by methods such as the use of tracers and advanced dynamic acquisitions. Principles of Medical Imaging for Engineers will be of use to engineering and physical science students and graduate students with an interest in biomedical engineering, and to their lecturers.BiotechnologyBiomedical engineeringSignal processingRadiologyBiotechnologyBiomedical Engineering and BioengineeringSignal, Speech and Image Processing RadiologyBiotechnology.Biomedical engineering.Signal processing.Radiology.Biotechnology.Biomedical Engineering and Bioengineering.Signal, Speech and Image Processing .Radiology.610.28616.0754Chappell Michaelauthttp://id.loc.gov/vocabulary/relators/aut762987MiAaPQMiAaPQMiAaPQBOOK9910349441503321Principles of Medical Imaging for Engineers2115703UNINA
