Patent ID: 11633175

Abstract:
A method for two-dimensional sheare wave elastography imaging comprises: a) acquiring B-mode ultrasound images of a target region in a body; b) selecting a region of interest inside the B-mode image; c) transmitting a shear wave excitation pulse focalized on an excitation region; d) measuring displacements of tracking focal points at different depths positions along laterally staggered tracking lines within the region of interest; e) determining elasticity parameters of the regions between two of the tracking focal points at the same depth and on at least two adjacent tracking lines as a function of the displacements caused by the shear wave at the tracking focal points; f) modifying the appearance of pixel(s) of the B-mode image inside the regions relatively to the grey-scale B-mode image as a function of elasticity parameters determined for the regions; and g) displaying the pixel(s) having a modified appearance at the corresponding pixel of the B-mode image.
