Semi-automated system for measurement of nuchal translucency thickness.
OBJECTIVE To estimate intersonographer and intrasonographer variance components of fetal nuchal translucency (NT) thickness measurement using the traditional manual approach and a new semi-automated system. METHODS A semi-automated method was developed for measurement of the NT. In this method, the operator places an adjustable box over the relevant area at the back of the fetal neck. The sys...
متن کاملAutomatic Nuchal Translucency Measurement from Ultrasonography
This paper proposes a fully automatic approach for computing Nuchal Translucency (NT) measurement in an ultrasound scans of the mid-sagittal plane of a fetal head. This is an improvement upon current NT measurement methods which require manual placement of NT measurement points or user-guidance in semi-automatic segmentation of the NT region. The algorithm starts by finding the pose of the feta...
متن کاملAre There Any Differences in Seismic Performance Evaluation Criteria for Concrete Arch Dams?
Differences between stress-based and strain-based criteria are investigated in seismic performance evaluation of the arch dams in time domain. A numerical model of the coupled dam-reservoir-foundation system is prepared with the finite element technique. Reservoir is modeled using the Eulerian approach as a compressible domain, and the foundation rock is assumed to be massless. Dynamic equilibr...
متن کاملIs there an association between increased nuchal translucency and autism?
Methods The study included all singleton infants born in Denmark, who had routine first trimester screening between January 1st 2008 and March 31st 2012. Children were divided into three groups by NT thickness: NT > 99th percentile (group 1), NT 95th-99th percentile (group 2), and NT < 95th percentile (group 3). Follow-up was undertaken for all children at 2 to 6 years of age, depending on date...
متن کاملMeasurement of fetal nuchal translucency thickness by three-dimensional ultrasound.
OBJECTIVE To investigate the feasibility and repeatability of nuchal translucency thickness measurement using three-dimensional ultrasound. METHODS Forty consecutive women with uncomplicated singleton pregnancies attending for Down syndrome screening at 11-14 weeks' gestation were included in this prospective crossover trial. Nuchal translucency thickness was measured using both two-dimension...
