Abstract: An ultrasonic diagnostic system and scanning technique are described for producing three dimensional ultrasonic image displays utilizing power Doppler signal information. In a preferred embodiment the power Doppler signal information is displayed in the absence of structural (B mode) information to reduce image clutter and provide three dimensional image segmentation. An ultrasonic scanning technique is presented for acquiring diagnostic three dimensional ultrasonic images of power Doppler intensity through manual hand scanning of a patient, without the need for specially fabricated scanning mechanisms or devices.

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.

Abstract: An ultrasonic diagnostic imaging system and method are described by which a fundamental frequency signal is transmitted into the body and harmonic (nonlinear) echo returns are received from the transmission. The harmonic echo signals are Doppler processed and displayed. The harmonic Doppler signals may be displayed alone, or in combination with a fundamental frequency or harmonic grayscale image. In a preferred embodiment harmonic signals returned from moving tissue are segmented on an intensity or frequency basis and displayed. The inventive apparatus and method provide highly resolved ultrasonic images of moving tissue which are substantially unobscured by image clutter from structures or tissue in the near field.
