The abnormalities of myocardial can be predicted quantitatively by analysing visualization of motion estimation in all or part of myocardial segment. To visualize the heart motion on myocardial, ultrasound image is evaluated globally using a differential optical flow technique that recursively applied a set of multi scale ultrasound image. A set of multi scale images is generated using approximation...
This study examines the variation of photoplethysmogram (PPG) morphology based on a sample by recording PPG finger tips from erectile dysfunction (ED) patients. Nine PPG indexes are calculated along with carotid intima-media thickness (CIMT) for all patients. The measured parameters are statistically analyzed and their association is shown in results section. These results show that PPG can be used...
In this paper, an automatic border detection of cardiac cavity in two-dimensional short axis echocardiography image is proposed. The method uses boundary and triangle equation to detect and reconstruct the border. The first step is determining the initial centers boundary. The second step is applying morphological and thresholding operations to eliminate noise and convert it into binary image. The...
