Abstract : Ultrasound imaging at 5 MHz has been demonstrated with an electronically scanned two-dimensional hybrid array and acoustic lens. A readout integrated circuit (ROIC), originally designed for infrared imaging, was hybridized to a 44x64 element piezoelectric array. The original readout electronics were also modified by adding a range gate. Real-time diffraction limited images of high reflectance targets were obtained with the f/1.0 doublet lens. This report summarizes the results of Phase I (12 months) of a three-year, two-phase program. Phase I demonstrated a prototype real-time imager using adaptations of existing infrared camera components. Phase II (24 months) will result in a laboratory demonstration prototype ultrasonic imaging system to prove the clinical utility of this technology.
