Zusammenfassung:Transmission tomography is considered for the case of the variable surface sensitivity of a detector. An equation is proposed for a 2D problem that is a correlation between measured intensity and the distribution of extinction coefficient. A method is developed that reduces reconstruction to searching for a system of linear algebraic equations. Simulation experiments demonstrate its advantages over beam tomography approximation.
