To develop a clinical device for monitoring FBM with a simplified mechanism, the multichannel pulsed Doppler device was achieved by modifying the ultrasonographic module and probe of a cardiotocograph. A new algorithm of signal processing with a high-accuracy displacement estimation technique produced real-time and continuous displacement calculations. In vivo measurements demonstrated that real-time output produced commendable quality in FBM tracking. The displacement of a few hundred micrometers because of FBM was measured successfully. The results suggest that quantitative assessments of FBM should be possible with this technique.
为了开发一种具有简化机制的用于监测胎儿呼吸运动（FBM）的临床设备，通过修改胎心监护仪的超声模块和探头实现了多通道脉冲多普勒设备。一种采用高精度位移估计技术的新信号处理算法实现了实时连续的位移计算。体内测量表明，实时输出在FBM跟踪方面产生了值得称赞的质量。成功测量了因FBM产生的几百微米的位移。结果表明，使用该技术对FBM进行定量评估应该是可行的。
