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.
