Ultrasonic monitoring of fetal respiratory movement including velocity measurements is described. Both proximal and distal walls of the fetal chest are imaged simultaneously. The time-position mode clearly defines fetal respiratory movement and rejects artefacts.
本文描述了包括速度测量在内的胎儿呼吸运动的超声监测。同时对胎儿胸部的近壁和远壁进行成像。时间-位置模式能清晰地界定胎儿呼吸运动并排除伪像。
