We given an inversion formula for the attenuated Radon transform
$$\bar \omega _L $$
for constant attenuation μ which is accurate up toO(µ4)

We also derive an integral equation of the second kind for the solution ofRμf=g. The implementation of both methods for the inversion ofRμ consists basically of a generalized filtered backprojection algorithm. Numerical examples are presented.
