Ultrasound Imaging Initiative.
Abstract
This objective of this project is to build a real-time 3-D ultrasound imaging system for combat casualty care. The high frame rate necessary for real-time 3-D 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. A network of high speed digital signal processors is currently being designed to implement the beamformer. A new transducer technology is also being explored for the transducer array. This technology should permit a 25-fold increase in the acoustic power delivered by a single array element without a corresponding increase in the excitation voltage. The array will be incorporated into a compact probe head designed to rock the array for real-time 3-D imaging. Besides the scanner development, an extensive set of software tools are being developed to provide easy and accurate analysis of the resulting 3-D data. These tools will allow real-time viewing of arbitrary two-dimensional planes through the data set and will allow quantitative assessment and display of the three-dimensional anatomy.
