超声诊断系统数据样本采集装置设计

摘要

目的:解决从超声诊断系统中实时采集大量数据样本的问题.方法:在PC平台上建立高速数据通道,由PC机完成采集控制、数据处理和文件存储的工作,PCI卡提供一个高速的数据输入通道,数据源接口板则完成信号的变换和端口连接.结果:通过采集程序实现了实时数据样本采集的高速度和大容量.结论:该数据样本采集装置可完成超声诊断系统大容量样本数据的高速采集,是一种经济有效的数据采集方法.%Objective To solve the problem of real data sampling in the ultrasonic diagnosis system. Methods A high speed data channel based on PC was established, which was made up of PC, PCI board and data source interface board. PC was used for data sampling control, data processing, and file storage. PCI board could give a high speed data input channel. And data source interface board was used for signal transformation and port connection. Results The high speed and huge sample data was accomplished with the help of sample program. Conclusion The data sampling device can get huge sample data from ultrasonic diagnosis system in high speed. and the method is economic and effective.[Chinese Medical Equipment Journal, 2011 ,32 ( 5) :17-18]
