Embodiment Construction
[0051] The tissue displacement estimation method using two scales proposed by the present invention will be described in detail in combination with specific embodiments and drawings as follows:
[0052] The embodiment of the present invention uses a computer program and a general ultrasonic scattering model simulation to obtain a one-dimensional radio frequency signal of a simulated tissue before and after compression. The tissue thickness is 60mm, and the elastic modulus at 0-30mm is 3 times that at 30-60mm. A simple one-dimensional model is used, so the strain at 0-30mm is 1 of the strain at 30-60mm. / 3. The amount of compression applied to the tissue is 3.33%, or 1.98mm; the center frequency of the probe is 3.5MHz, and the -3dB bandwidth is 2.0MHz. Because of the simple one-dimensional model, there is only one scan line; the sampling frequency of the radio frequency signal is 20MHz, Assuming that the propagation speed of ultrasound in the tissue is 1540m / s, therefore 1mm tissue...
