Anthropomorphic Cardiac Ultrasound Phantom With Coronary Arteries

Abstract

The cardiac anthropomorphic ultrasound phantom has been improved by the addition of two new features. An aorta with a bifurcation has been molded into the torso via a "lost wax" procedure. B-scan images of contrast medium and color-flaw Doppler images show flow patterns typical of peripheral vessels in Doppler phantoms. In addition, three coronary arteries have been attached to the externd surface of the ventricle. Contrast injection of aerated water in the coronary arteries are easily visualized in real-time Bscan images.
