Emboli generated in cardiac surgery can result in many postoperative neurological complications. There are many methods to reduce the amount of emboli or to block them. Nevertheless, many of methods have limitation. In this study, ultrasonic radiation force generated by phased array ultrasound is used to block emboli and the blocking effect is evaluated. We do vivo experiment on eight pigs (40kg)...
