We carried out a series of studies to improve the reproducibility of methods for ultrasonic myocardial tissue characterization using a stochastic approach to amplitude analysis of radiofrequency signals previously reported from our laboratory. Analysis of transducer scanner characteristics, data acquisition and processing, and data display from studies in tissue phantoms permit us to define some features of a parameter for expression of tissue character. The ratio of mean to standard deviation of the amplitude histogram from our system is explored as now implemented in our laboratory for reproducible measurements. The theoretical basis for understanding the utility of this method in defining tissue architecture and pathologic conditions requires further work.
我们开展了一系列研究，以提高使用随机方法对射频信号进行幅度分析来表征超声心肌组织的方法的可重复性，该方法此前已由我们实验室报道。通过对换能器扫描仪特性、数据采集与处理以及组织体模研究中的数据显示进行分析，使我们能够定义用于表达组织特征的参数的一些特性。目前在我们实验室实施的对系统幅度直方图的均值与标准差之比进行了探索，以实现可重复测量。理解该方法在定义组织结构和病理状况方面效用的理论基础还需要进一步研究。
