1 The Born Approximation The Born approximation is derived from high energy physics’ multiple scattering. It is the simpler of the two approximations and is a perturbation approach. 19) is smaller than the magnitude of the incident field ϕ0 . 2 The Rytov Approximation The Rytov approximation is another first-order approximation to the scattered field and is valid under different restrictions. It is also a perturbation method. 18). The first-order Born and Rytov solutions will provide information on the scattered field to be used in the reconstruction.

N − 1},{bl (n) , l = 0, . . . , N − 1} are one-dimensional complete orthonormal sets of basis vectors. 37) The Z-Transform The Z-transform is a generalization of the Fourier transform to the two-dimensional complex regime. 38) m,n=∞ where z1 and z2 are complex variables. The Z-transform of the impulse response of a linear shift invariant discrete system is called its transfer function. 39) This shows the transfer function of the systems, the ratio of the Z-transforms of the output, and the input sequences.

We consider an infinite space filled with a homogeneous loss-free acoustic medium with propagation velocity c0 . Imbedded in this medium is a loss-free object of constant density ρ = ρ0 and a spatially varying velocity distribution c(r). A sphere of radius a completely encloses the object. The Cartesian coordinates x, y, z are centred in this sphere. The assumption of a loss-free system means that η = Y = 0, and this removes the coupling between ϕ and A. The assumption of a constant density ρ = ρ0 reduces the remaining equation for ϕ, the scalar potential to the Helmholtz wave equation.
