Measurement of Nuchal Translucency Thickness for Detection of Chromosomal Abnormalities using First Trimester Ultrasound Fetal Images

TL;DR

This paper presents a method for measuring nuchal translucency thickness in first trimester ultrasound images to detect chromosomal abnormalities like Down Syndrome, using image segmentation and analysis techniques.

Contribution

It introduces a segmentation approach combining mean shift analysis and Canny operators for accurate measurement of nuchal translucency.

Findings

Average nuchal translucency thickness at 14 weeks is 1.87mm.

Segmentation techniques effectively identify the translucency region.

Measurement accuracy supports early screening for chromosomal abnormalities.

Abstract

The Nuchal Translucency thickness measurement is made to identify the Down Syndrome in screening first trimester fetus and presented in this paper. The mean shift analysis and canny operators are utilized for segmenting the nuchal translucency region and the exact thickness has been estimated using Blob analysis. It is observed from the results that the fetus in the 14th week of Gestation is expected to have a nuchal translucency thickness of 1.87 plus or minus 0.25mm.
