| 摘 要： | 为了在无创心功能检测中准确迅速地检测出脉搏波,获得有用的诊断信息,在临床医学上有效地防治疾病,设计了一种基于FPGA和Matlab的高速实时脉图信息处理系统.该系统以FPGA芯片为核心,利用FT245BM型快速USB接口芯片和HK-2000G脉搏传感器,实现了对脉搏信号的采集,在主机上运用VB和Matlab混合编程技术,采用均值微分,积分、模糊插值、希尔伯特黄变换、小波变换等算法,完成脉搏信息的时频处理.该系统通过软硬件滤波,去除了呼吸等干扰信号,能正确地实时显示、存储、打印数字化脉波图像信息,自动运算得到脉图特征参数.通过对不同人体脉图特征参数测试,脉图信息有效、可靠,在医学亚健康诊断及病态诊断和家庭医疗方面有广泛的应用价值.
