Abstract
A method for calibrating ultrasound equipment and ultrasound contrast agents are provided that utilize polystyrene microspheres as a broad-band in vitro calibration tool. In accordance with the method a suspension of polystyrene microspheres is provided in a liquid environment in a container having an acoustic aperture. The suspension of microspheres is continuously agitated during measurement of the backscatter from the suspension of microspheres and the ultrasound equipment or contrast agent is then calibrated or adjusted to a selected backscatter setting.
