ANTHROPOMORPHIC CARDIAC ULTRASOUND PHANTOM ABSTRACT OF THE DISCLOSURE Apparatus and method are disclosed for producing ultrasound readings of simulated blood flow through a model left ventricle or larger portion of the human heart, held inside a fluid filled chamber with membrane-covered windows, and through mitral and aortic valves cooperating therewith to provide a simulated human circulation flow free of reverberation artifacts and the like. Adjustable flow of a selected hydraulic fluid into and out of the chamber that also contains a plurality of ultrasound absorbing elements disposed oppositely to the ultrasound viewing windows is utilized to produce ultrasound signals picked up by an ultrasound transducer for processing in any known manner. A range of flow rate and systolic characteristics of a heart are readily simulated, to provide outputs substantially free of reverberations and ultrasound reflections from the inside walls of the chamber as well as the ultrasound absorbing elements.
