Abstract

Non-invasive quantitative measurement of blood flow currently remains a problem in the field of vascular diagnostics. In the past several years, nuclear magnetic resonance (NMR) has been developed as a viable method of non-invasively measuring quantitative blood flow in some limited areas of the body. Although its usefulness and practicality have been demonstrated, there remains a need for refinement of NMR systems Ito increase their accuracy and ease of measurement. One area of particular interest is the application of NMR in two-dimensional blood flow scanning which allows individual arteries to be located and their flows measured. The design presented in this thesis is an improvement to existing implementations of "gradient control'' systems used for two- dimensional ranging in NMR blood flowmetry. Very little documentation has been published on past implementations. Therefore, it is the intentions of the author to focus on the design implementation of the gradient control system rather than the physical theory underlying the use of gradient fields for ranging in blood flowmetry.
