Abstract :
Sonoelasticity imaging utilizes low frequency (i.e. ~100 Hz) vibrations in tissue or in elastic materials, and Doppler imaging of vibration patterns to detect and define abnormalities and flaws. Fundamental theoretical considerations of sonoelasticity imaging are reviewed in this paper, to predict the image of a small abnormality in a background of homogeneous elastic tissue. Comparisons from experimental work on elastic phantoms, and from finite element analyses, confirm the ability of vibration images to define small elastic inhomogeneities
