Embodiment 1
[0021] This embodiment discloses an elastic imaging method, such as figure 1 shown, including:
[0022] S1 first performs ultrasound imaging on the target tissue to obtain an ultrasound image.
[0023] In this step, the region of interest of the object to be detected may be excited by the acoustic radiation force, and ultra-high-speed ultrasound imaging is performed on the region of interest to obtain ultrasonic image data of the region of interest of the object to be detected. Exemplarily, the ultrasound image data may include at least one of RF (Radio Frequency, radio frequency) data, envelope data, and B-mode data.
[0024] S2 obtains the characteristic direction of the tissue from the ultrasound image, and obtains the characteristic direction through tissue segmentation and grayscale co-occurrence matrix processing. The characteristic direction can be the extension direction of the muscle fiber or the extension direction of the long axis of the blood vessel. an angle. F...

The characteristic direction can be the extension direction of the muscle fiber or the extension direction of the long a...
Embodiment 3
[0043] Based on the same inventive concept, this embodiment discloses an elasticity imaging system, including:
[0044] a feature orientation determination module for obtaining the feature orientation of the tissue from the ultrasound image;
[0045] The shear wave excitation module is used to respectively excite shear waves propagating along the extension direction of the tissue to be tested and the direction forming a preset angle with it according to the characteristic direction;
[0046] The ultrasonic module is used to excite longitudinal waves into the tissue to be tested through the ultrasonic probe, and the longitudinal waves will generate reflected echoes after reaching the tissue;
[0047] The shear wave feedback module is used to obtain shear wave velocity and shear wave dispersion curve according to the reflected echo; the tissue elasticity module is used to fit the shear wave velocity and tissue elasticity equation, according to the shear wave velocity and shear w...
