| 摘 要： | 基于空间几何原理和超声多普勒三角测量法,提出了一种胎头位置、宫颈扩张的自动测量方法,以替代产科临床使用的传统手工触诊法。研究建立了跟踪定位测量系统模型,讨论了可能引发测量误差的原因。设计并实现了超声多普勒跟踪定位系统,包括超声传感器系统、超声驱动/接收电路和测控系统软硬件。模拟测试表明,所设计的系统对胎头位置和宫颈开口的5次测量平均值绝对误差小于0.25cm,远小于传统手工触诊法的平均误差2.0cm。

| Abstract: | In order to replace the conventional method of vagina palpation which has been widely used in obstetrics,a new method for detecting fetal head position and cervical dilation automatically is proposed based on the analytic geometry of space and ultrasonic triangulation.A tracking (position) model is set up and kinds of factors which may cause detecting errors are discussed.A ultrasonic measurement system for body tracking (position) is developed.The error of average result from 5 times detection by this syst... |
