We consider the two-projection tomography problem, assuming a priori known prohibited region. We show that a modification of Ryser’s reconstruction algorithm gives a solution. We then study the relation of the switching graph for the solution sets with and without the prohibited region. Finally, we apply our idea to get a better reconstruction figure imposing prohibited region artificially.
