Area of Science:

Medical imaging
Fetal medicine
Computational biology

Background:

Increased nuchal translucency (NT) thickness is a significant indicator of fetal abnormalities, including cardiac defects and genetic syndromes.
Accurate NT measurement is crucial for effective first-trimester fetal disease screening.
Current methods for NT assessment can be subjective and time-consuming.

Purpose of the Study:

To develop and validate a semi-automated algorithm for accurate nuchal translucency (NT) thickness measurement.
To improve the reliability and efficiency of NT assessment in routine fetal ultrasound screening.
To reduce inter-observer variability in NT measurements.

Main Methods:

A modified level set algorithm was employed for semi-automated segmentation of the nuchal translucency region.
A regression model was utilized to determine the optimal direction for NT thickness measurement.
The algorithm was tested to evaluate its accuracy and error rate.

Main Results:

The developed algorithm demonstrated a high degree of accuracy in segmenting the NT region.
The semi-automated method achieved a measurement error rate of 4.5%.
The approach shows potential for consistent and reproducible NT thickness determination.

Conclusions:

The modified level set algorithm offers a promising semi-automated solution for accurate NT measurement.
This method can enhance the reliability of fetal ultrasound screening for major abnormalities.
Further validation in larger cohorts is warranted to confirm clinical utility.
