摘　　要：动脉血流频谱波形曲线上蕴含丰富的血流动力学信息,动脉重度狭窄、闭塞时,其上下游动脉的频谱形态会有特征性的改变,可通过上下游动脉的频谱形态来评估动脉狭窄、闭塞性病变。如何有效提取其中与诊断有关的血流参数,使诊断更准确,一直为国内外研究者所关注。本研究介绍了时域分析、频域分析、建模分析等当前血流频谱波形分析的主要研究方法及血流参数提取的研究进展,并对未来血流动力学特征性参数的研究方向进行展望。Blood flow spectrum waveform curve contains abundant hemodynamic information.When the artery is severely stenosis or occlusion,the spectral morphology of the upstream and downstream arteries will have characteristic changes.The spectral morphology of the upstream and downstream arteries can be used to evaluate the arterial stenosis and occlusion.How to effectively extract the blood flow parameters related to diagnosis and make diagnosis more accurate has always been the concern of researchers at home and abroad.In this study,the main research methods of current blood flow spectrum waveform analysis,such as time domain analysis,frequency domain analysis and modeling analysis,and the research progress of blood flow parameter extraction are introduced,and the future research direction of characteristic parameters of hemodynamics is prospected.
