Multi-mode ultrasonic elastography method and system

Abstract

The invention provides a multi-mode ultrasonic elastography method and system, and the method comprises the steps: transmitting an ultrasonic signal according to a preset sequence in an acquisition period, and alternately carrying out the signal acquisition for ultrasonic strain imaging and the signal acquisition for shear wave elastography on the tissue of a to-be-observed region according to the preset sequence, so as to obtain signal data; processing the signal data to obtain first tissue information data about tissue displacement and strain and second tissue information data about tissue elasticity modulus; and based on the first tissue information data and the second tissue information data, in combination with a time sequence of ultrasonic original signal acquisition, acquiring tissue displacement, strain and tissue elasticity modulus information of the to-be-observed area in one acquisition period. According to the scheme, ultrasonic strain imaging and shear wave elasticity imaging can be simultaneously carried out on the tissue through one-time sequence acquisition, and related information such as strain and elasticity of the tissue at any moment or in a stress state is measured.

AI Technical Summary

Benefits of technology

This patented describes a new way to study how blood vessels develop when they burst into place during medical procedures. By measuring their size changes over time it becomes possible for physicians to diagnose diseases earlier by analyzing these measurements compared against previous data from patients' own body fluids collected beforehand. These advancements allow researchers to better identify areas where there may have been problems caused due to excessive pressure applied through them while still being able to accurately determine its properties.

Problems solved by technology

This patented technical problem addressed by these inventors relates to improving the accuracy and effectiveness of medical diagnoses through analysis of both hard and soft tissures caused by sonopathies like echocardiograms. Current techniques involve either multiple scans from one subject to another or separately acquired images without combining them together.
