AI Technical Summary

Technical Problem

Existing technologies rely on human experience in detecting valvular regurgitation, which suffers from high subjectivity, poor consistency, and low repeatability, resulting in inaccurate measurement results and low efficiency.

Method used

Principal component analysis was used to identify the regurgitation region of the heart valves, determine the main extension direction, and quantify the regurgitation state through morphological characteristic parameters, including the width of the constriction neck of the regurgitation jet and the radius of the proximal isokinetic surface, to provide objective detection results.

Benefits of technology

It achieves a high degree of consistency and repeatability in the detection results of heart valve regurgitation, eliminates subjective errors in manual measurement, and improves detection efficiency and accuracy.

Abstract

本发明提供一种心脏瓣膜反流的检测方法、系统和介质,所述方法包括:获得由心脏瓣膜结构或功能异常引起的反流区域识别;对所述反流区域进行主成分分析,确定对应心脏瓣膜反流的主延伸方向;根据所述主延伸方向确定所述反流区域的至少一个形态特征参数;根据所述形态特征参数确定心脏瓣膜反流状态信息。该方法通过主成分分析对反流区域的空间分布进行特征分解,将复杂的不规则血流形态转化为具有明确物理意义的主延伸方向,基于该主延伸方向计算形态特征参数,可消除人工测量瓣膜反流参数时因主观视角差异或经验不足导致的随机误差,使不同操作者、不同检测条件下获得的瓣膜反流评估结果具有高度一致性和可重复性。
