Abstract

Electron paramagnetic resonance (EPR) imaging of free radicals in objects is performed from projections using magnetic field gradients. Low frequency (2 GHz or less) continuous-wave EPR instrumentation with capability for up to three-dimensional spatial and up to four-dimensional spectral-spatial imaging are commonly used for biological samples. Image reconstruction is performed by filtered-backprojection methods. The basic concepts of EPR imaging, instrumentation, data acquisition, signal processing, and image reconstruction are discussed. Strategies for enhancement of image quality and resolution have also been discussed in this Chapter. A few examples that are representative of biological applications are presented.
