Abstract :
A new technique for the simultaneous measurement of left ventricular epicardial and endocardial wall dynamics is presented. X-rays scattered from the surface of the heart are used to monitor motion at the epicardial surface and iodine fluorescence induced in the blood pool is used to monitor motion of the endocardium. Continuous wall thickness measurements throughout the cardiac cycle are obtained.
