Abstract
An ultrasonic diagnostic imaging system is provided which utilizes a multivariate processor to discriminate between Doppler power signals which were produced by moving tissue, and Doppler power signals which were produced by fluid flow. Discriminated moving tissue Doppler power signals are displayed in a three dimensional spatial presentation.

A method for producing three dimensional ultrasonic images of a moving organ or tissue within the body comprising the steps of:
- transmitting ultrasonic waves over a volumetric region of the interior of the body containing an organ or tissue which is to be imaged;
- receiving ultrasonic Doppler information signals from spatial locations within said organ or tissue;
- processing said ultrasonic Doppler information signals to determine the Doppler power intensity received from said locations within said organ or tissue where tissue is in motion;
- and
- displaying the Doppler power intensity received from said organ or tissue motion on a spatial basis in a three dimensional presentation.
A method for producing ultrasonic images of a moving organ or tissue within the body comprising the steps of:
- transmitting ultrasonic waves over a volumetric region of the interior of the body containing an organ or tissue which is to be imaged;
- receiving ultrasonic Doppler information signals from spatial locations within said organ or tissue;
- processing said ultrasonic Doppler information signals with a multivariate process to determine the Doppler power intensity received from said locations within said organ or tissue where tissue is in motion;
- and
- displaying the Doppler power intensity received from said organ or tissue motion on a spatial basis.
An ultrasonic imaging system for producing ultrasonic images of a moving organ or tissue within the body comprising:
- a multielement ultrasonic transducer which receives ultrasonic signals from said organ or tissue;
- a beamformer, coupled to said transducer, for processing said ultrasonic signals to produce beams of ultrasonic information;
- a Doppler processor responsive to said ultrasonic information for producing Doppler power signals corresponding to spatial locations within said organ or tissue;
- a multivariate processor, responsive to said Doppler power signals, for discriminating Doppler power signals corresponding to moving tissue from Doppler power signals corresponding to fluid flow;
- and
- a display for displaying Doppler power information corresponding to tissue motion on a spatial basis.
