Abstract: The talk will start with a brief overview of medical ultrasound imaging. Then, simplifications of complex wave propagation for their use in formulating inverse problems to reconstruct images of various tissue properties will be presented, in particular with the problem statements and our contributions on “beamforming" as the generation of spatially-resolved echo images from acquired multi-sensor temporal traces; “elastography" as the reconstruction of tissue viscoelasticity maps from internal motion; and "ultrasound computed tomography” (USCT) as the tomographic reconstruction of local sound-speed and other propagation parameters. Estimating scattering distributions in the tissue will also be demonstrated as an inverse-problem of deconvolution, with a particular use in the context of modeling tissue-specific scattering within ray-tracing based approximations aiming at real-time ultrasound image simulation for medical training. Recent contributions on deep variational networks for USCT image reconstruction will conclude this talk.
