胎儿运动是监测胎儿神经发育和评估胎儿健康的宝贵信息来源。目前，胎儿运动可以由母亲评估，也可以通过分析超声图像来检测。这两种方法的长期监测都很复杂，因为产妇自我评估的敏感度和特异度相对较低，而且无法自动分析超声图像。此外，超声波换能器将能量传递到人体内，潜在地危及胎儿健康。本文提出了一种可供选择的胎动监测方法。该方法从孕妇腹部的无创记录中估计和分析胎儿心电向量图(VCG)。将所确定的胎动与同时进行的超声记录评估的胎动相比较，所提出的方法的结果与超声图像相一致。此外，该方法还可以通过分析连续的胎儿VCG之间的旋转矩阵来量化旋转角度，为长期监测胎儿运动提供了一种工具，具有更高的特异性。
Fetal movement is a valuable source of information to monitor the neurological development of the fetus and assess fetal health. Currently, fetal movement can be assessed by the mother or detected by analysis of ultrasound images. Long-term monitoring of movement is complicated with both these methods as maternal self-assessment has a relatively poor sensitivity and specificity and automatic analysis of ultrasound images is not available. Moreover, ultrasound transducers transmit energy into the body, potentially endangering fetal health. In this paper, an alternative method for fetal movement monitoring is presented. This method operates by estimating and analyzing the fetal vectorcardiogram (VCG) from non-invasive recordings on the maternal abdomen. The determined fetal movement is compared with that assessed from a simultaneously performed ultrasound recording; the results of the presented method are consistent with the ultrasound images. In addition, the presented method enables quantification of the rotation angles by means of analysis of the rotation matrix between consecutive fetal VCGs, providing a tool for long-term monitoring of fetal movement with increased specificity.
