Abstract : This report documents the first year of a 3-year project to develop a field prototype Advanced Imaging System (AIMS). This prototype will consist of a lightweight, portable ultrasonic imaging system containing a two-dimensional transducer array, computer hardware and software for real-time 3-D holographic image reconstruction and visualization, and a stereovision headset for 3-D image display. During the reporting period, technology was developed to acquire and reconstruct 3-D images in the laboratory, using ultrasonic holography with a point transducer and 2-axis mechanical scanning, and to render these images using volume visualization. In addition, a 3-D imaging testbed system based on 'sequential B-scan' technology was developed and placed at Medical Army Medical Center to gain extensive physician experience with in-vivo 3-D ultrasound.
