Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical image processing, and in particular, to an elastic imaging method and device. Background technique [0002] For a long time, in order to detect the hardness and elasticity information of biological tissues, doctors often use the method of freehand palpation, but freehand palpation has great limitations and dependence. The elastography technology for the purpose of detecting the elastic modulus of biological tissues emerged as the times require. [0003] Among them, the principle of ultrasonic elastography is that by applying an external excitation to the detected tissue, under the action of physical laws such as elastic mechanics and biomechanics, the internal tissue will produce a response, such as displacement, strain, and velocity distribution will produce differences. Then, through digital signal processing and digital image processing technology, the displacement and st...
