A variably attenuated x-ray transform is shown to be invertible via an integral formula for the inversion of the exponential x-ray transform.The attenuation must be known and constant in a convex set containing the unknown emitter. However the attenuation can be otherwise arbitrary.If

. Of course F. Natterer [Numer. Math., 32 (1979), pp. 431–438] showed that the values of the Fourier transform of the emitter can be obtained from the Fourier transform of the exponential x-ray transform. In essence however the basic method is analytic continuation from the set

There is a great deal of current interest in inverting attenuated Radon transforms which occur in single photon emission tomography. These transforms are special cases of generalized Radon transforms
