Abstract
We investigate herein transmission mode ultrasonic imaging of 3-D fluid media from single-frequency multiview synthetic data. The technique used is based upon a Newton-Kantorovitch algorithm, which yields an iterative solution of the non-linear ill-posed inverse scattering problem, through a linearization and a Tikhonov regularization procedure. We lay emphasis on the robustness of the algorithm.
