Abstract:
A system for three-dimensional imaging of an object volume containing moving ultrasound scatterers, comprising:an ultrasound transducer array for transmitting ultrasound beams and detecting ultrasound echoes reflected from said object volume at a multiplicity of sample volumes;means for acquiring velocity data derived at least in part from ultrasound echoes reflected by the ultrasound scatterers, each velocity datum corresponding to a respective one of said multiplicity of sample volumes;memory means for storing velocity data for each of said multiplicity of sample volumes;means for retrieving a source velocity data set from the velocity data stored in said memory means, said source velocity data set including only velocity data lying in a predetermined range;means for projecting the velocity data in said source velocity data set onto a first image plane, thereby forming a projected velocity data set representing a first projected image;a display monitor; andmeans for displaying said first projected image on said display monitor.
