Key result
New anthropomorphic cardiac ultrasound phantom successfully simulates human anatomy for ultrasound and Doppler imaging applications.
Why the study?
A new phantom simulating human cardiac anatomy is needed for applications in ultrasound imaging, Doppler, and color-flow Doppler imaging.
The development of an anthropomorphic cardiac ultrasound phantom provides a simulated environment for testing and measuring flow patterns in ultrasound and Doppler imaging applications.

A new phantom is described which simulates the human cardiac anatomy for applications in ultrasound imaging, ultrasound Doppler, and color-flow Doppler imaging. The phantom consists of a polymer left ventricle which includes a prosthetic mitral and aortic valve and is connected to a mock circulatory loop. Aerated tap water serves as a blood simulating fluid and ultrasound contrast medium within the circulatory loop. The left ventricle is housed in a Lexan ultrasound visualization chamber which includes ultrasound viewing ports and acoustic absorbers. A piston pump connected to the visualization chamber by a single port pumps degassed water within the chamber which in turn pumps the left ventricle. Real-time ultrasound images and Doppler studies measure flow patterns through the valves and within the left ventricle.
