Providing baseline information on the quantitative measurement and visualization of physiological structures in a range of disciplines, this comprehensive yet accessible handbook draws on contributions from leaders in the field under the editorship of the highly respected John G. Webster. It represents one of the first major single volumes in the field and offers reviews and discussions from the editorial board of the journal Physiological Measurement. Focusing on the electrical, mechanical, and chemical engineering aspects of instrument design and use, imaging modalities, and data analysis, the book covers sensors, amplifiers, signal processers, displays, and imaging techniques.
