CA 2157313

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.

Système diagnostiqueur ultrasonique et technique de balayage permettant de produire des affichages d'images ultrasoniques tridimensionnelles utilisant de l'information de signal de niveau de puissance Doppler. Dans une version préférée, l'information de signal de niveau de puissance Doppler est affichée en l'absence d'information structurale (mode B) afin de réduire les échos parasites à l'écran et de produire la segmentation d'images tridimensionnelles. Une technique de balayage ultrasonique est présentée pour l'acquisition d'images ultrasoniques tridimensionnelles de niveau de puissance Doppler par balayage manuel du corps d'un patient, sans nécessiter de mécanismes ni de dispositifs de balayage fabriqués spécialement.
