Abstract

The invention discloses a multifrequency shear wave amplitude analysis-based ultrasonic elasticity imaging technique and relates to the field of medical imaging and the field of man-machine interfaces. The ultrasonic elasticity imaging technique comprises the following steps: modulating a drive pulse of a shear wave to enable the shear wave to generate different angular frequency shear waves; measuring vibration amplitudes of a particle in a tissue caused by the shear wave at different frequencies; comparing the particle vibration amplitudes in the shear wave under different angular frequencies to obtain a shear wave angular frequency corresponding to the maximal particle vibration amplitude; and acquiring the wave velocity of the shear wave or a shear modulus of the tissue or the wave velocity of the shear wave and the shear modulus of the tissue according to the angular frequency. According to the ultrasonic elasticity imaging technique, the amplitude is subjected to measurement of arelative value, rather than measurement of an absolute value, and amplitude information has higher interference resistance when being measured, relative to conventional phase information in the priorart. The ultrasonic elasticity imaging technique can be implemented through two ultrasonic vibration elements, is easy to realize portability, and has a great application potential in the field of man-machine interfaces.

Description

technical field [0001] The invention relates to the field of medical imaging and the field of man-machine interface, in particular to an ultrasonic elastic imaging technology based on multi-frequency shear wave amplitude analysis. Background technique [0002] Ultrasound elastography is an emerging tissue imaging technology in recent years, which can be used to obtain the elasticity information of human tissue, and the normal tissue and diseased tissue of the human body show different elasticity, so this technology has been widely studied in the field of medical diagnosis and apply. [0003] On the other hand, the human-machine interface can collect physiological signals of the human body, and can obtain the motion intention of the human body through processing, which can be further used to control external devices. And tissues such as skeletal muscle also have different elastic coefficients under different exercise states. Therefore, ultrasound elastography can provide hu...
