In order to reduce the influence of scatter for radiography and increase the precision of the reconstructed object, the double-axis radiography system is proposed on the basis of using specific collimators. The double-axis radiography system has one collimator on each radiography axis, and the two collimators have different collimating angles. with such system the simulation radiography is carried out. The results show that the scatter from one axis to the other axis in radiography is large, and it is mainly from the front window. And it is reduced greatly by putting the lead block in the direction from front window to the detector on the other axis. The collimated angles for the FTO double-axis radiography is 2.24° and 1.15° according to the combining information and requirement of scat
