Acoustic Inverse Scattering for Breast Cancer Microcalcification
Abstract
An advanced scalar inverse scattering theory developed by Colton, Kirsch, and others in the inverse scattering community can determine the shape of scatterers with size on the order of the wavelength. In addition to size and number, the morphology of breast microcalcifications is an important diagnostic indicator. Our hypothesis is that the linear sampling method (LS), when augmented with a method for estimating the inhomogeneous Green's function for wave propagation in the breast, can be translated to an acoustic imaging system to detect, localize, and characterize microcalcifications in breast phantoms using data from the farfield scattering measurements. To realize this goal, we have implemented a new data acquisition system for water tank measurements, designed breast phantoms including appropriate hard scatterers of known shape, and developed numerical methods for both simulation and image reconstruction. Year 2 will focus on the evaluation of these methods.
