A three-dimensional ultrasound imaging system includes an ultrasound probe to direct ultrasound waves and to receive reflected ultrasound waves from a target volume of a subject under examination. The ultrasound probe is swept over the target volume and the reflected ultrasound waves are conveyed to a computer wherein successive two-dimensional images of the target volume are reconstructed fo form a three-dimensional image of the target volume. The three-dimensional image is displayed on the monitor of the computer. A user interface allows a user to manipulate the displayed image. Specifically, the entire displayed image may be rotated about an arbitrary axis, a surface of the displayed image may be translated to provide different cross-sectional views of the image and a selected surface of the displayed image may be rotated about an arbitrary axis. All of these manipulations can be achieved via a single graphical input device such as a mouse connected to the computer.
Système d'imagerie tridimensionnelle par ultrasons comportant un capteur d'ultrasons servant à diriger les ultrasons et à capter les ultrasons réfléchis par un volume cible du sujet en cours d'examen. Ledit capteur balaye le volume cible et les ondes réfléchies sont transmises à un ordinateur qui assemble deux images bidimentionnelles successives du volume cible pour reconstituer une image tridimensionnelle présentée sur l'écran de l'ordinateur. Ladite image peut être manipulée par l'utilisateur à l'aide d'une interface et en particulier subir des rotations globales autour d'un axe arbitraire ou certaines de ses surfaces peuvent être translatées de façon à fournir différentes coupes de l'image ou tourner autour d'un axe arbitraire. Toutes ces manipulations peuvent se faire à l'aide d'un simple dispositif de commande graphique tel qu'une souris branchée sur l'ordinateur.
