In this paper, we proposed a novel procedure to detect the calcification boundary and measure the calcification area in the tunica media coronary artery using an intravascular ultrasound image (IVUS). The calcification of interest is near the tunica intima region. This study used an Otsu threshold, a morphological operation and an empirical threshold in detecting the contour of the calcification,...
The intravascular ultrasound (IVUS) modality is used by the medical practitioner to detect the coronary artery disease called atherosclerosis, which is the hardening of the artery wall and subsequently narrow the blood vessel. In this paper, we present the segmentation method for detecting the lumen border of a coronary artery using IVUS images. The automated segmentation used is Otsu threshold, binary-morphological...
In this paper, we present the lumen coronary artery border detection using intravascular ultrasound (IVUS) images. The approach make used of texture analysis based on Binary Robust Independent Elementary Features (BRIEF) and Chi-square classification. This proposed method can detect the boundary and calculate the area within the lumen coronary artery border. This method was tested on thirty samples...
In this paper we present an automated segmentation method to detect the boundary between adventitia and media on the cross sectional view of the artery of patients who have plaques. The problem encounter is that the boundaries of the adventitia, media, intima and lumen are embedded when plaques exist. Moreover, the artery disease has damaged the tissue layers. This paper proposed a method in segmenting...
