In this paper we investigate the equation for the imaginary part of the scattering amplitude in scalar theory with trilinear interaction. In other words, we investigate the agreement of the exponential behavior of the imaginary part of the amplitude in the Regge region with the corresponding Bethe-Salpeter equation in the ladder approximation.
