Abstract
A clutter and sensitivity phantom for calibrating an acoustic beam generating clinical Doppler ultrasound instrument, comprising: a fluid-filled tank into which the ultrasound instrument probe is immersed; first and second sound scattering belts; an acoustic beam splitter intermediate the ultrasound probe and the first and second sound scattering belts, the acoustic beam splitter being oriented at a predetermined angle relative to the ultrasound instrument and to respective ones of the first and second signal scattering belts for splitting and directing the acoustic beam generated by the ultrasound instrument so as to be reflected off both of the first and second sound scattering belts at an identical angle, whereby portions of the acoustic beam reflected off of the first and second sound scattering belts may be separately or simultaneously monitored.
