Abstract

A new method for determining the time distribution of blood-flow within a vessel using x-ray imaging is presented. The method has been validated by both stationary and pulsatile flow experiments. The method is capable of determining average flow values under conditions of high pulsatile flow. The application of this method to cine-recorded data of aortic blood flow in dogs is in good agreement with the known shape of the aortic flow distribution. An application of this method to evaluate aortic regurgitation is shown.
