Ultrasound imaging with FWI framework

Jinji Li, Kristopher A. Innanen

Full waveform inversion (FWI) has established itself as a crucial technique in earth science, providing high accuracy and resolution in geophysical imaging. Inspired by its success in earth science, recent studies have begun exploring the application of FWI to medical imaging using ultrasound, suggesting that it could serve as an efficient alternative to conventional approaches such as magnetic resonance imaging (MRI) and X-ray computed tomography (CT). In particular, frequency-domain FWI is well suited for this application, as it allows efficient modeling of selected frequencies and avoids the need for fine time discretization, eliminating concerns about insufficient temporal sampling. Building on these preliminary investigations, we further examine the feasibility of frequency-domain FWI for ultrasound medical imaging through a controlled synthetic scenario. We analyze the advantages and potential limitations of this approach and outline directions for more detailed exploration and future development.
