AI Technical Summary

Technical Problem

Existing technologies cannot accurately capture the instantaneous interaction details between blood flow and the vessel wall at the microvascular scale, nor can they quantify and track the non-uniform distribution of contrast agents and blood flow turbulence. This results in the inability to identify high-risk areas and predict damage risks during microvascular interventional procedures, affecting the safety and accuracy of the interventional procedures.

Method used

By analyzing ultrasound images over time, the non-uniformity of echo enhancement at the contrast agent-tissue interface is extracted. Combined with vascular wall stress characteristics and blood flow parameters, a comprehensive quantitative assessment of the interaction between blood flow and the vascular wall is achieved, generating dynamic monitoring parameters and damage risk warning signals.

Benefits of technology

It enables high-precision dynamic monitoring of the interaction between blood flow and vessel wall during microvascular interventional procedures, improving the timeliness and accuracy of potential damage risks and providing a scientific and reliable basis for real-time intervention decisions.

Abstract

This application relates to the field of medical imaging technology and discloses an interventional procedure assessment system and method based on ultrasound image temporal analysis. The method includes: acquiring continuous image sequences and synchronous blood flow signals of a microvascular region; extracting contrast agent and tissue echo characteristics and analyzing the degree of echo enhancement non-uniformity; if this degree exceeds a preset threshold, extracting vessel wall stress characteristics from the blood flow signals and determining the estimated value of local vessel wall stress distribution by combining the spatial correspondence of contrast agent characteristics; extracting blood flow signal fluctuation characteristics, determining the abnormal range of blood flow parameters and obtaining the probability of potential injury risk; if the probability exceeds a warning threshold, analyzing vessel wall stress adjustment characteristics to determine the time window of the risk event; fusing the risk window and the estimated stress distribution value to generate dynamic monitoring parameters, obtaining an interactive comprehensive evaluation value, adjusting the monitoring threshold accordingly, and generating an interventional procedure injury risk warning signal. This application improves the timeliness and accuracy of injury risk warning in microvascular interventional procedures.
