Real-Time 3-D Ultrasonic Diagnostic Imager for Battlefield Applications
Abstract
This final report describes the accomplishments of a two phase, three year technology demonstration program whose goal was "to develop a 2-D acoustic array which incorporates VLSI technology and demonstrate it's imaging capability in a portable ultrasound imager". During Phase I (year 1), Lockheed Martin demonstrated ultrasound imaging at 5 MHz using an electronic scanned, two-dimensional hybrid transducer array and an acoustical lens. The hybrid array was constructed by mating a readout integrated circuit (ROIC) originally designed for infrared imaging to a 42x64 element piezoelectric array. In Phase II (years 2 & 3), a camera system suitable for medical imaging was designed and key components were demonstrated. This system included: a 128x128 element piezocomposite array mated to new ROICs specific designed for medical imaging; supporting electronics and signal processing; and a high performance acoustical lens. In-vitro real-time images were made of test objects and biological specimens. Demonstration of a portable imager was not realized.
