  • A conjugate gradient-neural network technique for ultrasound inverse imaging 

    Broschat, Shira L.; Zhang, Xiaodong; Flynn, Patrick J. (World Scientific Publishing, 2002-06)
    In this paper, a new technique for solving the two-dimensional inverse scattering problem for ultrasound inverse imaging is presented. Reconstruction of a two-dimensional object is accomplished using an iterative algorithm ...
  • A numerical study of conjugate gradient directions for an ultrasound inverse problem 

    Broschat, Shira L.; Zhang, Xiaodong; Flynn, Patrick J. (World Scientific Publishing, 2004-12)
    In ultrasound inverse problems, the integral equation can be nonlinear, ill-posed, and computationally expensive. One approach to solving such problems is the conjugate gradient (CG) method. A key parameter in the CG method ...
