NICHD Fetal Growth Studies

NICHD胎儿生长研究的首要目标是：1)确定4个种族/民族胎儿的最佳生长标准；2)确定与预期胎儿生长下降相关的因素。相关的目标是开发算法，以更好地估计胎儿体重和确定最佳分娩时间。一个主要的成就是开发了一个数据库，用于存储二维和三维超声图像和伴随的生物特征数据。该数据库是一个有价值的资源，为后续工作，旨在确定特定的生长尺寸，如骨长，体积或器官的大小。这些图像的数据库是开源软件。

The overarching goals of the NICHD Fetal Growth Studies are to 1) determine optimal growth standards for 4 racial/ethnic groups of fetuses and 2) to identify factors associated with decrements in expected fetal growth. Related goals are in developing algorithms for better estimating fetal weight and in determining the optimal timing of delivery. A major accomplishment was in the development of a database for the storage of 2D and 3D ultrasonology images and accompanying biometric data. This database is a valuable resource for follow on work aimed at determining specific growth dimensions such as bone length, volumes or organ size. The database for the images is open source software. Successful completion of the study is schedule for September 2014
