RESUMO

This work was developed with the purpose of obtaining Tomoqraphic Images by Nuclear Magnetic Resonance (NMR). It was elaborated in two distinct ways. One of them was the analysis of slice selection by selective excitation, already proposed by other authors. To do this, we developed a package of computer programs that simulates the behavior of a spin system from the Bloch Equation solution. The other was the adaptation of a NMR spectrometer already existing in our laboratory to obtain tomographic imaqes. The results show that our prototype can produce imaqes tomographics slices with width less than 1 cm.
