Vascular Ultrasound Data during Enhanced External Counterpulsation for Predicting Coronary Artery Disease
There are thousands of pictures of blood flow spectrum curves in carotid and brachial artery. So we only listed one person's carotid artery and brachial artery blood flow ultrasound images before, during and after counterpulsation.
Blood flow spectrum curves in carotid and brachial artery analyzed by image processing are used to establish transfer function establishment based on 12-order ARX model. Two hundred and nineteen transfer function characteristics were calculated, including coefficient A, B, Zero(zx), Pole(px) and Pole(py) between CAD and control groups before EECP, during EECP and immediately after EECP. The classification was performed by Extreme Learning Machine.
