Abstract

A three-dimensional ultrasound imaging system includes an ultrasound probe to direct ultrasound waves to and to receive reflected ultrasound waves from a target volume of a subject under examination. The ultrasound probe is swept over the target volume along a linear scanning path and the reflected ultrasound waves are conveyed to a computer wherein successive two-dimensional images of the target volume are digitized. The digitized two-dimensional images can be used to generate a three-dimensional image with virtually no delay. 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.
