Abstract

An approximate analytical solution of the problem of attenuation and distance-dependent resolution effects in single photon emission tomography is presented for the case of a uniform absorbing medium. The algorithm obtained is a generalization of the Bellini and co-workers formula correcting for the single attenuation effect and is derived by means of Fourier transforms only. The method has been validated on mathematical phantoms as well as on physical data.
