  • A comparison of material classification techniques for ultrasound inverse imaging 

    Zhang, Xiaodong; Broschat, Shira L.; Flynn, Patrick J. (Journal of the Acoustical Society of America, 2002-01)
    The conjugate gradient method with edge preserving regularization (CGEP) is applied to the ultrasoundinverse scattering problem for the early detection of breast tumors. To accelerate image reconstruction, several different ...
  • Inverse imaging of the breast with a material classification technique 

    Manry, Charles W.; Broschat, Shira L. (Journal of the Acoustical Society of America, 1998-03)
    In recent publications [Chew et al., IEEE Trans. Blomed. Eng. BME-9, 218–225 (1990); Borup et al., Ultrason. Imaging14, 69–85 (1992)] the inverse imaging problem has been solved by means of a two-step iterative method. In ...
