Ultrasonic imaging with narrow aperture phased array
Electronics and Communications in Japan (Part III: Fundamental Electronic Science), 2002AbstractThis paper describes the method of narrow aperture phased array ultrasonic computed tomography (NAPA‐CT), conceived for three‐dimensional imaging with increased resolution and speed in the field of clinical diagnosis. By reducing the size of the transducer in the thickness direction, a beam is formed such that the focal region of the phased ...

Ultrasonic receive beamformer with phased sub-arrays
The Journal of the Acoustical Society of America, 1997An ultrasonic receive beamformer includes transducers forming receive signals that are applied to sub-array processors. Each sub-array processor includes at least one phase shifter and a summer, and each phase shifter is responsive to at least one of the transducer signals to shift the transducer signal by a respective phase angle and to apply the ...

Two-dimensional phased array of ultrasonic transducers
The Journal of the Acoustical Society of America, 1991A two-dimensional ultrasonic phase array is a rectilinear approximation to a circular aperture and is formed by a plurality of transducers, arranged substantially symmetrical about both a first (X) axis and a second (Y) axis and in a plurality of subarrays, each extended in a first direction (i.e.
