Abstract

An exact formula approach to nonuniform attenuation correction in single-photon emission computed tomography (SPECT) was discussed. The formula admits a numerical implementation via a direct generalization of the filtered backprojection (FBP) algorithm. The formula can be used for fast computing of an efficient first approximation for more complicated SPECT reconstruction techniques.
