Optical and digital processing of tomographic data is presented and discussed in the context of a Fourier reconstruction algorithm applied to phantom radionuclide sources of nuclear medicine. The point spread function of the reconstruction process is discussed in relation to the angular sampling of frequency space and investigated using coherent optical techniques. Approximations due to gammaray attenuation in the source and the non-stationarity of the point spread function of the detector system are also presented.
