Abstract:

The main objective of this project is the development of accurate physical models and efficient numerical algorithms suitable for diffraction tomographic reconstruction of the compressibility, acoustic attenuation, and mass density of the prostate through a multielement transurethral ultrasound transceiver. Unlike conventional ultrasound imaging, which is non-quantitative and affected by speckle artifacts, three-dimensional tomographic solution of the inverse acoustic scattering problem has the potential to quantitatively reconstruct the detailed acoustic properties of the prostate from measurements of the scattered radiation field. However numerous challenges must be confronted before such a proposition becomes feasible in real-world applications. It is well-known that problems in inverse scattering, in addition to being mathematically complex and computationally intensive, are also particularly ill-posed and ill-conditioned.1, 2
