Stereoscopically display three dimensional ultrasound imaging
First Claim
1. A method of ultrasound imaging of anatomical structures of an organism comprising the steps of:
- (a) providing ultrasound energy;
(b) propagating said energy through an organism having anatomical structures therein such that said energy is reflected from said anatomical structures;
(c) receiving said energy after reflection from said anatomical structures;
(d) measuring parameters of the reflected energy resulting from reflection from said anatomical structures;
(e) converting said parameters to three dimensional image data representing images of said anatomical structures, said three dimensional image data comprising a range of shades of display color;
(f) transforming said image data into independent, angularly displaced right and left three dimensional video signals representing right and left eye three dimensional stereoscopic components of an image of said anatomical structures from a first perspective, said transforming step including the steps of creating a three dimensional view from said first perspective of said three dimensional image data, said first perspective representing one of said right or left eye stereoscopic components and rotating said three dimensional image data from said first perspective to a second perspective and creating a second three dimensional view from said second perspective, said second perspective representing the other of said left and right eye stereoscopic components; and
(g) displaying said right and left stereoscopic components of said image on respective separate, independent right and left video displays to thereby provide a stereoscopic three dimensional view of said anatomical structures.

Abstract
A stereoscopically displayed three dimensional ultrasound imaging system derives image data from an ultrasound imaging apparatus including a two dimensional ultrasound transducer array, reconstructs the image data into a three dimensional model, and displays right and left stereoscopic three dimensional image components of the model on corresponding right and left video display devices of a stereoscopic viewing unit. The system includes a system computer interfaced to the imaging apparatus and a pair of image channels, each including a three dimensional display processor, and a video display device. The three dimensional display processors receive polygon image data, reconstruct it into a three dimensional form, and select image data representing a three dimensional view from a selected perspective. The system computer controls the display processors to present mutually angularly displaced views of the same three dimensional image to form the stereoscopic image components.
