Real Time Intraluminal Ultrasonic Imaging



This image is a 5 mm by 5 mm frame from a real-time image sequence of a diseased coronary artery. It was obtained with a 1.2 mm diameter, 64 element circumferential ultrasound array operating at 20 MHz. This array has been positioned inside an angioplasty balloon used for interventional procedures. With this device, high resolution cross-sectional images of coronary arteries can be obtained in real-time as interventional procedures are performed. Current research is trying to improve the basic image quality of this device. In addition, we are studying intraluminal methods to image blood flood, image tissue elasticity and monitor stent deployment. Work on this system is funded by the National Institues of Health and is conducted in collaboration with Endosonics Corporation of Rancho Cordova, CA.
