摘要：

We present a new reconstruction approach to emission computerized tomography based on image restoration by exact inversion of the degradation transform. The approach also allows us to determine the attenuation coefficient from the degraded image without any additional measurements. The degraded image is reconstructed by the optimization technique as the least deviating solution from the given model. The results of numerical experiments with computer generated data are presented.
