Signals and Systems in e-Health presents the mono dimensional physiological signals (physical quantities varying over time spontaneously or evoked), two dimensional (medical images), and three dimensional (movies revealing inside or outside the human body) that can be collected to unveil the body's pathophysiological condition, as well as systems able to capture these signals. The hardware and software implantation of technical platforms dedicated to the practice of e-health uses of these signals and system--telemedicine, in particular--is developed in detail. Some augmentative devices--for deficient physiological organs integrated in telemedical systems--are also subject of this book.
