RESUMO
We describe in this work the development of hardware and software necessary to implement the Magnetic Resonance Imaging (MRI) techniques. Our major subjects were the construction of an acquisition and control system which allowed the operation of a pulsed Fourier NMR spectrometer as a NMR Tomograph; further we oriented the developing of a NMR spectrometer whose parameters could be easily reconfigured by the controlling system. As a result we obtained a sophisticated equipment which allows, more than the proposed, working with high resolution spectroscopic techniques and spectroscopy in solids. Since the basic techniques employed in NMR and CT Tomographs are well known, a great emphasis was also given on the understanding of the image reconstruction techniques that constitutes today the frontier of research in this area. The results obtained with the system described here are considered good, comparable to the results from commercial units developed in cooperation with imaging groups located in universities abroad.
