Design of a quantitative analysis software system for myocardial contrast echocardiography / 生物医学工程学杂志

ABSTRACT

This article reports a quantitative analysis software system for myocardial contrast echocardiography (MCE). It can measure the signal intensity of grayscale images and power Doppler images, draw the time-intensity curves of variations on the intensity of microbubbles scattering in subendocardial layer and subepicardial layer with the pulsing intervals, and estimate the hemodynamic parameters by nonlinear regression analysis. This system has been applied to a study on 20 healthy volunteers, and the results suggest that the software has the capacity for bringing the quantitative analysis of MCE to success. The MCE software system conforms to the DICOM standard and can be integrated into PACS.
