Abstract:

This objective of this project is to build a real-time 3D ultrasound imaging system for combat casualty care. The high frame rate necessary for real-time 3D imaging is obtained using a synthetic aperture beamforming technique. The technique uses a fraction of the transmit pulses required by a conventional imaging system and permits very rapid image acquisition with no degradation of image quality. The hardware and software development for our beamformer, that uses a network of high-speed digital signal processors for generating data at the desired speed, has been completed. The fabrication of a new multi- layer transducer array has been completed as well. This array has been incorporated into a compact probe head designed to rock the array for real-time 3D imaging. The assembly of the final system is currently under way. Besides the scanner development, an extensive set of software tools have been developed to provide easy and accurate analysis of the resulting 3D data. These tools allow real-time viewing of arbitrary two-dimensional planes through the data set and quantitative assessment and display of the 3D anatomy.
