SYSTEM AND METHOD FOR ACQUIRING, SEGMENTING, AND RECONSTRUCTING TWO-DIMENSIONAL ULTRASOUND DATA USING A MECHANICAL ANGLE SCANNER WITH GEOMETRIC CALIBRATION

Abstract

The invention proposes a system and method for acquiring, segmenting, and reconstructing two-dimensional ultrasound data using a mechanical arc scanning device. The system acquires the output image stream from the original ultrasound device, identifies the useful image region, the display interface region, and receives rotational angle data from the angle sensor. Upon detecting a change in geometric state from the display interface, the system separates the frame sequence into acquisition segments, self-calibrates the geometric information for each segment, and then maps and stitches it to a common mechanical reference frame to create a three-dimensional ultrasound mass. The rotational angle data is the primary source for spatial mapping; image morphology variation is used only for secondary cross-checking.
