Real Time 3-D Ultrasonic Diagnostic Imager for Battlefield Application
Abstract
This report presents progress achieved through the second 12 months of Phase II of a two phase technology development program. During Phase I, Lockheed Martin demonstrated ultrasound imaging at 5 MHz using an electronically scanned, two-dimensional hybrid transducer array and acoustical lens. The hybrid array was constructed by mating a readout integrated circuit (ROIC) originally designed for infrared imaging to a 44x64 element piezoelectric array. Thus far in Phase II, developments include: a new ROIC specifically designed for ultrasound imaging; a 128x128 Transducer Hybrid Assembly (THA), transmitter electronics and transducers, a wide-angle diffraction limited acoustical lens and ancillary electronics for readout, signal processing and display. The design of these subsystems was described in the 1996 Annual Report. They are now functional and system integration is underway. Thitial results with water tank imaging of simple targets are presented in this report. The laboratory demonstration system being developed will produce real-time (30Hz), two-dimensional images with 1 mm resolution in three dimensions and will be capable of collection of three-dimensional data for real-time volume imaging. -__________________________________________________________________________
