Abstract:

In this article, we study reconstruction of nonuniform attenuated SPECT data and present analytic reconstruction formulae which are similar to Novikov's inversion formula. Furthermore, we extend Natterer's results.

Key words: Nonuniform attenuated, SPECT data, attenuated Radon transform, Novikov's inversion formula
