Abstract

The invention discloses a soft tissue superelasticity characteristic representation method. The method comprises the following steps: on the basis of ultrasonic radiation force shear wave imaging technology, detecting the wave velocity of a shear wave spread in a target tissue under the press-in depth of a probe, and besides an elongation ratio lambda which is used for balancing deformation in a press-in direction, introducing a parameter xi to describe a deformation state in the transverse direction; and finally, introducing the detected parameters into an inversion formula so as to obtain superelasticity characteristic parameters of the target tissue.

Description

technical field [0001] The invention relates to the technical field of ultrasonic elastography, in particular to a soft tissue hyperelastic feature characterization method. Background technique [0002] Elastography is a method that can non-invasively monitor the mechanical properties of biological tissues. In the past twenty years since the concept was proposed in 1991, elastography, as a new type of medical detection method, has received extensive attention both in terms of method development and clinical application. Elastography mainly includes the following steps: [0003] 1: Apply external or internal incentives to the target soft tissue; [0004] 2: Through the existing medical imaging technology (such as ultrasound, nuclear magnetic resonance, etc.), detect the mechanical response of soft tissue to excitation, including deformation or shear wave propagation; [0005] 3: Through inverse analysis, the elastic or viscoelastic properties of soft tissue can be reversed...
