Paper Abstract

A computerized fluoroscopy method for isolating low fluoroscopic image contrast, which results during the flow of iodinated contrast materials through cardiovascular structures is described. This technique requires applying one of a family of recursive filtering algorithms which have been designed to isolate time varying image contrast. Applications of this technique for intravenous angiography are described. Hardware implementation of these algorithms also is described and preliminary results on human subjects is presented.
