Inverse Scattering Theory
TLDR
This paper discuss a fully 3D nonlinear algorithm that results in a 3D quantitative estimate of breast tissue characteristics and a refraction corrected reflection algorithm (RFCR) that utilizes these estimates. Expand

Three-dimensional nonlinear inverse scattering: Quantitative transmission algorithms, refraction corrected reflection, scanner design and clinical results
TLDR
We show the feasibility of quantitative whole breast ultrasound imaging of the breast tissue speed and attenuation, and concomitant refraction corrected reflection imaging, using data collected from an early prototype. Expand
