COMPOSITE SHEAR-WAVE AND QUASI-STATIC ELASTICITY IMAGING METHOD

The present invention relates to the technical field of ultrasound imaging, and in particular to a composite shear-wave and quasi-static elasticity imaging method. The following technical solution is used: first, pre-scanning a target area, and obtaining a rough comparison relationship curve; then, performing real-time scanning, and performing optimization correction on the rough comparison relationship curve, so as to obtain an accurate comparison relationship curve; and finally, calculating a real-time shear modulus of a large area according to a real-time relative elasticity value of the large area, thereby realizing accurate real-time elasticity imaging. The beneficial effects are as follows: the advantages of two elasticity imaging modes, i.e., quasi-static elasticity imaging and single-point shear-wave elasticity imaging, are combined, such that the imaging effects of an imaging area being large, a frame rate being high and a measurement structure being an accurate shear modulus are achieved, and the qu
