1. A medical diagnostic ultrasound system which develops three dimensional images of flow or motion and structure in a volumetric region of the body comprising:
- an ultrasonic transducer for receiving ultrasonic echoes;
a tissue image processor for processing ultrasonic echoes to produce tissue display information;
a flow and motion image processor for processing ultrasonic echoes to produce or motion flow display information; and
a three dimensional image processor for processing said tissue and said flow or motion display information in an interleaved sequence to form a three dimensional image.

Abstract
A medical diagnostic ultrasound system is described in which ultrasonic B mode tissue information and Doppler flow information is acquired from a volumetric region of the body and processed in an interleaved sequence to render a three dimensional image. The three dimensional rendering processes the B mode and Doppler flow information to give priority to tissue information, flow information, or a blend of the two.

6. A method for rendering a three dimensional ultrasonic image pixel from a plurality of overlapping ultrasonic two dimensional image pixels of tissue and flow comprising the steps of:
-
a) comparing a partially rendered three dimensional ultrasonic tissue image pixel with one of said two dimensional tissue image pixels, and setting the value of said partially rendered three dimensional ultrasonic tissue image pixel on the basis of said comparison;
orb) comparing a partially rendered three dimensional ultrasonic flow image pixel with one of said two dimensional flow image pixels, and setting the value of said partially rendered three dimensional ultrasonic flow image pixel on the basis of said comparison; and c) comparing a partially rendered three dimensional ultrasonic flow image pixel with one of said two dimensional tissue image pixels, and setting the value of said partially rendered three dimensional ultrasonic image pixel on the basis of said comparison. - View Dependent Claims (7)
