Abstract:

In the development of a L band three dimensional ESR imaging system, a software package of application programs was written with MATLAB (version 6.1),  which handles auto-processing of spectral data, and reconstruction of ESR spati al (1D, 2D, 3D) imaging and spectral-spatial imaging. The software can displa y different types of images reconstructed from the spectral data and distribution of spin density in the paramagnetic samples. In addition, this software is cap able of generating useful visible information, which can be applied in the chara
cterization of the spin density distribution of paramagnetic species, as well as in the oxygen diffusion process in chemical reactions.

Key words: ESR, imaging, ESR-CT, filtered back projection, spin density, software
