Claim 12:
13. The tomographic imaging method of claim 11, further comprising performing a mapping function using a cross-domain operator for mapping the total wavefield in the computational domain from each grid point in the computational domain to each corresponding grid point in the residual domain, wherein the mapping function performs a series of integration operations, comprising:
a first operation performing, for each grid point in the residual domain, an integral with a Green's function centered at a grid point in the residual domain over each grid point in the computational domain;
a second operation computing an updated total wavefield resulting from an interaction of the total wavefield in the residual domain with the background medium inside the residual domain; and
a third operation performing, for each grid point in the computational domain, an integral with a Green's function centered at a grid point in the computational domain over each grid point in the residual domain.
