A comparison of material classification techniques for ultrasound inverse imaging
(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
(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 ...
