The possibility of using the nonlinear effect of the third-order combination wave generation is analyzed for medical diagnostic goals. This effect makes it possible to implement the tomography of a spatial distribution of acoustical nonlinear parameters. The contributions by both purely third-order nonlinear scattering and twofold second-order nonlinear scattering are estimated. These two parallel developing competitive processes create two similar effects, which, however, can be separated. The two-dimensional experimental scheme, which contains just three transmitters with broadband modulation of two primary waves and one receiver, is proposed. The model numerical and physical experiment results are presented.
