The invention discloses a method for
intravascular ultrasound multi-slice
shear wave elastography. The method comprises the following steps of recording an original
ultrasound echo signal of a tissue to be detected; enabling an interventional
ultrasound array probe to generate
acoustic radiation force by virtue of a short-pulse
signal controlled by a computer; emitting ultrasonic pulse beams for many times to accept and detect a propagation process of
shear waves generated by the
acoustic radiation force; analyzing the propagation speed of the
shear waves in the tissue to be detected to obtain a
wave speed distribution image of the
shear waves in the tissue; performing
wave speed mapping on the shear
waves at each position in the tissue to be detected to obtain a quantitative elastic image of the intravascular tissue. The method has the advantages of real time performance, quantification, high speed,
high resolution and the like; a multi-
array element intravascular
transducer array is used for performing
vascular wall tissue elastic information quantitative analysis to excite and track the shear
waves; the further popularization and application of intravascular
elastography are favorably promoted, and the early diagnosis capability of people in cardiovascular diseases is enhanced.
