胎儿生长发育的各项参数是产科研究的重点:随着超声技术的发展,三维超声开始广泛应用于临床。在胎儿产前检测方面,三维超声体积自动测量技术主要用于建立超声观测胎儿生长的体积参数,了解其与孕龄、出生体重、畸形的相关性。体积参数在头部、胸部、腹部、四肢及胎盘方面均有研究,是较为先进的测量技术。 Fetal growth and development of the parameters of the obstetric research focus: With the development of ultrasound technology, three-dimensional ultrasound began to be widely used in clinical. In fetal prenatal testing, three-dimensional ultrasonic volume measurement technology is mainly used to establish the volume parameters of fetal growth observed by ultrasound, to understand its correlation with gestational age, birth weight, deformity. Volumetric parameters in the head, chest, abdomen, limbs and placenta have been studied, is more advanced measurement techniques.
