Advanced Beamformers for 3D Ultrasound Systems Deploying Linear and Planar Phased Array Probes

摘要

The present report outlines the development of an advanced digital ultrasound imaging technology leading to a next-generation field-portable 4D diagnostic imaging system. The proposed technology consists of: Adaptive beamforming algorithms to provide high image-resolution for ultrasound diagnostic systems; 3D visualization imaging techniques to assist imaging during field-deployable minimally invasive operations; time-reversal pulse design for ultrasound signals to eliminate aberration effects, which cause fuzziness in reconstructed ultrasound images; and investigations on computing architectures and planar ultrasound sensor arrays allowing system integration of the proposed technologies as a compact- portable system for field-deployable operations.
