APPARATUS AND METHOD FOR PROVIDING A DYNAMIC 3D ULTRASOUND IMAGE
First Claim
1. A method of imaging a three-dimensional (3D) ultrasonic image of a vessel, comprising the steps of:
- (a) providing a cardiac cycle time of a subject;
(b) providing a plurality of ultrasonic images acquired at a plurality of successive positions of the vessel, wherein the plurality of ultrasonic images corresponding to the plurality of positions are acquired during a plurality of acquiring time periods each of which is at least equal to the cardiac cycle time, and providing a positioning system to position each of the plurality of positions;
(c) providing a plurality of sets of cardiac cycles respectively corresponding to the acquiring time periods, wherein each of the plurality of cardiac cycles has a plurality of unit phases;
(d) catching a specific ultrasonic image for each of the plurality of positions, wherein the specific ultrasonic image corresponds to a specific one of the plurality of unit phases; and
(e) reconstructing the specific ultrasonic images for the plurality of positions to provide the 3D ultrasonic image of the vessel.

Abstract
A system and method thereof for capturing and reconstructing a dynamic 3D ultrasound image of a blood vessel are provided. The present system includes a ultrasound transducer, a motor positioning system, an electrocardiograph, a microprocessor for processing ultrasound images and signals capturing by the ultrasound transducer, and a monitor displaying the dynamic 3D ultrasound image. The motor positioning system controls the ultrasound transducer to capture 2D ultrasound images of the blood vessel at several locations in a predetermined urea. During the capturing process, capturing times, electrocardiograms and 3D locations of those captured 2D ultrasound images are simultaneously recoded. Finally, those captured 2D ultrasound images are reconstructed to the dynamic 3D ultrasound image of the blood vessel according to the time bases based on the phases of the electrocardiograms.
