Four highly advanced technologies - biomedical imaging, radar, navigation and remote sensing - have brought the importance of electromagnetic imaging into prominence. Because of the relatively independent development of these technologies, however, there has so far been little attempt to put together a unified approach to the electromagnetic imaging principles that are applicable to all four disciplines. This volume fills this gap. It introduces research and development engineers, graduate students and senior undergraduate students to the basic principles and techniques involved in electromagnetic image reconstruction and image processing. An attractive feature of the book is that in addition to covering the fundamental science behind imaging and the algorithms most commonly used, it also provides technological implementation examples of imaging. All the concepts and applications of electromagnetic imaging considered essential are discussed, while the programs listed will be of help to beginners who require a starting point for reconstructing images, as well as for manipulating and processing these.
Signal processing is addressed at the levels of both images and the time domain electromagnetic signals and basic tools available for processing images are described. The application of wavelets and wavelet transforms to electromagnetic imaging systems is presented as a general approach to processing and understanding electromagnetic images. Providing wide-ranging, yet detailed, coverage, Electromagnetic Imaging in Science and Medicine features the following chapters: Introduction; Fundamentals of Image Processing; Signals in Science and Medicine; Fundamentals of Image Reconstruction; Mathematics of Signals and Image Reconstruction; Wavelet Transforms for Electromagnetic Images; Magnetic Resonance Signal Analysis Using Wavelets; Vision-Based Underwater Cable Tracking; Three-Dimensional Image Reconstruction; References.
