NMR Probeheads for Biophysical and Biomedical Experiments is essential reading for anyone in the field of NMR or MRI, from students to medical or biological scientists performing experiments under certain physical and/or geometrical conditions, unattainable by conventional or available probes. The material guides the reader through the most basic and comprehensive stages in accomplishing a correct probe design, from a very basic oscillating circuit to much more elaborate designs. The general principles of matching and tuning probes are presented while some typical examples are explained in detail. Preventing NMR probes from becoming radiating antennas, multiple tuning principles, and steps for evaluating and debugging a probe are all covered. For the first time, these principles are applied for both homogeneous and heterogeneous resonators. The book is accompanied by a CD that contains software utilities used to exemplify the stages of different probe designs.
