Abstract : This program seeks to apply a solid state, staring, ultrasonic hybrid array to demonstrate the first real-time, portable, C-scan diagnostic ultrasound medical imaging system with three-dimensional (3-D) capability for battlefield and trauma care. The objective of Phase II of the BUDI program is to demonstrate a prototype ultrasonic imager capable of high quality ultrasound imagery suitable for 3D reconstruction. Phase II is a two year effort. This report covers the first year of that two year period. The plan for this year was to design and begin fabrication of a bi-static ultrasound imager employing a 128x128 receive array and multiple broad area transmitters to insonify the area of interest. The system incorporates a physical beam former (ultrasonic lens), receive array, custom electronics to operate the array and control system timing, a signal processor for image construction and a commercially available PC (personal computer) as the user interface. A separate high resolution video monitor, transmit transducers, and power amplifier complete the system. All portions of this system were analyzed to assure that the prototype could meet the performance requirements.
