Principles And Clinical Applications Of Magnetic Resonance, Rao P. Gullapalli, Teresa T. Evans, Roger M. Hawk
Journal of the Arkansas Academy of Science
A review is presented which covers the basic theory of nuclear magnetic resonance (NMR) with regard to angular momentum, magnetic moments, and the classical mechanical description of the NMR experiment. Longitudinal (T,) and Transverse (T2) relaxation times are defined as well as the basic pulse sequences used for their measurement. In particular, the 180°-t-90° and the Hahn Spin Echo pulse sequences are described in detail. Basic Magnetic Resonance Imaging (MRI) theory is discussed with regard to slice selection, frequency encoding, and phase encoding to define the imaged volume element. The equations defining the amount of Tt , T2 , and …

Several definitions of the term "engineer" are presented, discussed, and contrasted with the term "scientist". These definitions demonstrate the fundamental differences between engineers and scientists and their professions The engineering method is compared with the scientific method and the value of each is discussed. Several aspects of engineering education are covered. The need for more liberally educated engineers is emphasized and the impact of computers on engineering education and the engineering profession is discussed. The value of a good science foundation in an undergraduate engineering program is also stressed. An engineering education is only as good as the engineering educators …
