Summary
Accurate coronary artery segmentation from X-ray angiograms is crucial for diagnosing heart disease. This study explores vessel extraction and enhancement techniques to overcome challenges like overlapping vessels and poor contrast in coronary angiography.
Area of Science:
- Cardiovascular imaging
- Medical image analysis
- Biomedical engineering
Background:
- Coronary heart disease is a leading global health concern.
- Coronary angiography is the gold standard for assessing coronary artery disease.
- Interpreting angiograms is challenging due to vessel overlap and poor contrast.
Purpose of the Study:
- To investigate coronary vessel extraction and enhancement techniques.
- To evaluate algorithms for coronary vessel segmentation in X-ray angiograms.
- To address limitations in current coronary angiography image analysis.
Main Methods:
- Review of coronary vessel extraction algorithms.
- Analysis of enhancement techniques for X-ray angiograms.
- Comparative study of segmentation algorithm capabilities.
Main Results:
- Identified key challenges in coronary vessel segmentation: low contrast, deformable vessel shapes, and bone shadows.
- Evaluated various techniques for improving vessel visibility and extraction accuracy.
- Presented the performance of significant coronary vessel segmentation algorithms.
Conclusions:
- Effective coronary vessel extraction and enhancement are vital for accurate diagnosis.
- Advanced algorithms are necessary to overcome inherent limitations in X-ray angiograms.
- Further research into segmentation techniques can improve cardiovascular disease assessment.
