Ultrasound Imaging Initiative
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. A beamformer capable of generating data for real-time 3D imaging has been implemented using a network of high speed digital signal processors. Optimized assembly code has been written for this system. A new multi-layer transducer array has been developed for improved electrical matching and noise performance. A prototype array has been incorporated into a compact probe head designed to rock the array for real-time 30 imaging. 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 will allow quantitative assessment and display of the 3D anatomy.
