Claim 15:
16. The tomographic imaging method of claim 15, wherein the solving of the optimization problem, further comprises:
inverting the PDE operator for an initialized current image of the internal structure of the object to determine a Jacobian of the scattered wavefield with respect to the current image of the internal structure of the object;
updating the current image of the internal structure of the object by minimizing a cost function between the measurements of the total wavefield and a total wavefield synthesized by combining the Jacobian of the scattered wavefield and a quasi-Newton descent direction of the cost function with respect to the image of the internal structure of the object; and
projecting the current image of the internal structure of the object onto a constrained total variation penalty function.
