Area of Science:

Medical Imaging
Cardiovascular Technology
Biomedical Engineering

Background:

Optical Coherence Tomography (OCT) provides high-resolution intravascular imaging.
Accurate segmentation is crucial for quantitative analysis of vascular changes like neointimal hyperplasia (NIH).
Existing methods may lack automation and robustness for complex intravascular OCT data.

Purpose of the Study:

To develop and validate a novel automatic segmentation technique for intravascular OCT images.
To enable precise lumen area extraction and stent strut detection.
To facilitate quantitative morphological analysis of in-stent neointimal hyperplasia (NIH).

Main Methods:

A hybrid approach combining Fuzzy C-Means (FCM) clustering and Wavelet Transform (WT) was employed.
Frequency-domain OCT scans of the human femoral artery were analyzed.
The method focused on inner luminal contour extraction and stent strut localization.

Main Results:

The automatic segmentation achieved high accuracy in extracting lumen contours and stent struts.
An average overlap value of 0.917 ± 0.065 was observed compared to manual segmentation.
The algorithm successfully identified an average of 6.7 ± 0.5 struts per OCT image.

Conclusions:

A fast and robust automatic segmentation algorithm using FCM and WT was successfully developed.
The technique provides accurate lumen border extraction and stent strut detection in intravascular OCT.
This automated approach is suitable for quantitative morphological analysis of in-stent neointimal hyperplasia.
