Monitoring fetal wellbeing is a compelling problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity (movement), well-being, and later developmental outcome. We have recently developed an ambulatory accelerometer-based fetal activity monitor (AFAM) to record 24-hour fetal movement. Using this system, we aim at developing signal processing methods to automatically detect and quantitatively characterize fetal movements. The first step in this direction is to test the performance of the accelerometer in detecting fetal movement against real-time ultrasound imaging (taken as the gold standard). This paper reports first results of this performance analysis.
监测胎儿健康状况是现代产科学中一个亟待解决的问题。临床医生越来越意识到胎儿活动（胎动）、健康状况与后期发育结果之间的联系。我们最近开发了一种基于动态加速度计的胎儿活动监测仪（AFAM），用于记录24小时的胎儿胎动。利用该系统，我们旨在开发信号处理方法，以自动检测并定量表征胎儿胎动。朝这个方向迈出的第一步是针对实时超声成像（被视为金标准）测试加速度计在检测胎儿胎动方面的性能。本文报告了该性能分析的初步结果。
