Fast reconstruction of tissue elastic modulus image by ultrasound.

Most technologies for tissue elasticity imaging are now based on measurement of stain distribution, since they are more suited to real-time processing than reconstruction of elastic modulus images. However, to obtain more quantitative information about tissue elastic properties, it is necessary to reconstruct tissue elastic modulus images. There, we developed a new method for reconstructing tissue elastic modulus images at high speed and with high precision based on a modified 3-D finite-element model. In this paper, we verify the validity of the method based on a modified 3-D finite-element model, using simulations and phantom experiments.
