Paper Abstract

Coded apertures are used in tomographic imaging systems to improve the signal-to-noise ratio (SNR) of the apparatus with a larger aperture transmissions area while maintaining the spatial resolution of the single pinhole. Coded apertures developed from uniformly redundant arrays (URA) have an aperture transmission area of slightly over one half of the total aperture. Computer simulations show that the spatial resolution of a SPECT apparatus using a URA generated coded aperture compared favorably with theoretical expectations and has a SNR that is approximately 3.5 to 4 times that of a single pinhole camera for a variety of cases.
