目的:分析胎儿实时三维显像过程中扫查时间、技巧、手法等对胎儿面部图像采集的影响。方法:采集2013年1~8月420例产科实时三维超声检查的结果,对其面部图像采集情况进行系统分析。结果:产科实时三维超声,胎儿面部图像采集的优劣与检查时机、孕妇体位改变、操作者的手法技巧等有密切的关系。结论:运用实时三维超声诊断技术在观察胎儿面部图像时,图像采集存在一定的技巧和方法,与经验积累密切相关,懂得这些技巧和方法,运用该技术行产科检查将会用最短的检查时间取得最理想的目的图像。
OBJECTIVE: To analyze the effect of scanning time, technique and technique on fetus facial image acquisition in real-time three-dimensional imaging of fetus. Methods: 420 cases of obstetric real-time three-dimensional ultrasonography were collected from January to August in 2013. The facial image acquisition was systematically analyzed. Results: Obstetric real-time three-dimensional ultrasound, fetus facial image acquisition advantages and disadvantages of examination timing, pregnant women position changes, the operator’s hand techniques are closely related. Conclusion: There are some techniques and methods of real-time three-dimensional ultrasound in fetus facial image observation, which are closely related to experience accumulation. With these techniques and methods, obstetric examination using this technique will be obtained with the shortest examination time The ideal destination image.
