Mid-diastole Frame Detection using Echocardiography Images

Applied image processing and ML algorithms to detect mid-diastole frames in echocardiography for mitral valve stenosis diagnosis.

Mid-diastole Frame Detection using Echocardiography Images

This project aimed to assist in the diagnosis of mitral valve stenosis by detecting the mid-diastole frame in echocardiography image sequences. By combining classical image processing with machine learning techniques, the system automatically identifies the optimal frame for analysis.

Description:
Applied image processing and machine learning algorithms to detect the mid-diastole frame in echocardiography images. The system supports diagnostic workflows by highlighting the most clinically relevant frame for measuring mitral valve area.

Tools & Technologies:
MATLAB, K-Means Clustering, Circular Hough Transform

Outcome:
Achieved an average frame difference of 1.40 frames compared to expert-selected frames (gold standard by echocardiologists), showing strong agreement and clinical viability.
