【摘要】 本文主要介绍在PCI图像采集系统的基础上,由B超序列图像重建出全方向M型心动图。通过梯度算法、曲线拟合算法等图像处理技术获得心动图波形函数,采用自回归谱估计分析获得较为满意的结果。谱分析方法为心脏病的临床诊断提供了一种新的方法。更多还原

【Abstract】 This paper is based on the image sampling system with PCI series image grab board.Discretional bearing gray-time graph,namely M-mode echocardiography in all directions is first rebuilt from M-mode ultrasonic serial images.Gradient arithmetic,curbe fitting arithmetic and some other image-processing techniques are used to get the discrete function of the wave of M-mode echocardiography in all directions.The experiments have indicated that the result of AR spectral analysis is satisfactory.Spectral estimation method provides a new way for clinical heart disease diagnosis based on the contemporary Ultrasonic.更多还原
