Zusammenfassung

Two-dimensional pulsed electron spin resonance (ESR) imaging was developed in two frequency ranges (radio frequency at 370 MHz and X-band at 9.5 GHz) using the Fourier imaging (FI) and filtered back projection (FBP) technique. A comparison and evaluation of FI and FBP images in both frequency ranges shows the superiority of the FBP method under the given conditions. Benefits and drawbacks of the different frequency ranges are analyzed with respect to the signal-to-noise ratio and the disturbing influences of the skin effect. Examples for the mapping of dynamic properties (e.g., relaxation times, diffusion coefficient) are given. Functional imaging is illustrated using variable temperature for discriminating radiation-induced differences in physical sample properties.
