Explicit Inversion of the Helmholtz Equation for Ultra-Sound Insonification and Spherical Detection
When variations are small, it reduces to the straight line case.
It reduces to the Born approximation when the scatterer is small compared to the wavelength of the sound.
It is a three dimensional treatment and includes contributions from none-straight line paths.
