This article describes the hardware and software components of two systems designed for quantitative analysis of data obtained during myocardial contrast two-dimensional echocardiography. One system is meant for off-line analysis of data, whereas the other is designed for on-line analysis, especially in the operating room. The algorithms used for data transfer, selection of appropriate frames, data alignment, derivation of time-intensity plots, and curve-fitting and parameter generation are described in some detail. It is hoped that this information will be of use to others who work in the field of myocardial perfusion imaging.
本文描述了两个用于心肌对比二维超声心动图数据定量分析的系统的硬件和软件组件。一个系统用于数据的离线分析，而另一个则设计用于在线分析，特别是在手术室中。详细描述了用于数据传输、选择合适帧、数据对齐、时间-强度曲线推导以及曲线拟合和参数生成的算法。希望这些信息对从事心肌灌注成像领域工作的其他人有用。
