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 schemes [1-6] 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. The aim is to investigate a new ultrasonic sensing and imaging technology that would lead to the design of portable, compact and field deployable 3D ultrasound diagnostic systems. The performance characteristics of the proposed diagnostic systems include minimization of the aberration effects and significant improvement in image resolution to allow for tissue identification and 3D tomographic imaging of internal body-organs. The adaptive processing schemes of this study are characterized as Dual-Use technologies and have been tested in operational active sonars of the Canadian Navy [1,4-6]. TRUNCATED
