English Abstract

Coronary Angiography is emerging as clinically robust modality for diagnosis and surgical planning for coronary heart diseases.

Angiography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins and the chambers.

There are different medical imaging modalities used, the most important method is Magnetic Resonance Imaging (MRI) that represents an accurate diagnosis and high precision results by three dimensional visualization of image.

This research is designed to develop an efficient and accurate segmentation technique of Cath images.

The proposed technique is based on the watershed algorithm, which is applied to the gradient magnitude of the image via MATLAB software.

A combination of many algorithms is applied for arteries to detect irregularities or blockages.

A comparison technique before and after ink injection in the vessels to illuminate the contrast is implemented.

This research has proved that using Watershed Segmentation is the better technique to detect blockages before ink injection, and using Median Filter with Image Subtraction is the better technique to detect blockages after ink injection.
