Abstract:
In this paper is presented the research and development of a new myocardial contrast echocardiography (MCE)-based quantitative analysis system for myocardial microcirculation. The system can measure the values of A, beta, A x beta, A-EER (endo-epi ratio of A), beta-EER and A x beta-EER from the signal intensity of real-time 2-D grayscale images and power Doppler images; it can draw the time-intensity curves to indicate the variation of the intensity of microbubbles scattering in subendocardial layer and subepicardial layer with the varying of myocardial segments; and it can estimate the hemodynamic parameters by nonlinear regression analysis. So the MCE software system has brought the quantitative analysis of real-time MCE to success.
