基于虚拟仪器的心音采集与分析系统设计

The designment of heart sound acquisition and analysis system based on virtual instruments

开发了一种新型的电子心音信号采集与分析系统,该系统以心音传感器和计算机自带声卡为基础,实现了心脏听诊从传统单一的"听"转变为可视、可听的多角度分析,结合LabVIEW和Matlab强大的数据分析能力实现了心音信号的采集、去噪、保存、分析等功能,可作为临床心脏诊断的辅助设备。

A new type of electronic heart sound signal acquisition and analysis system was developed. The visual, audible multi-angle analysis system comes to heart sound sensors and a computer sound card, combined with LabVIEW and Matlab power- ful data analysis capabilities,this system has functions such as achieve a heart sound signal acquisition, de-noising, preservation, and analysis, which can be used as an implementation for heart auscultator.
