Automatic ultrasonic robotic array
2013 IEEE International Ultrasonics Symposium (IUS), 2013A novel, autonomous reconfigurable ultrasonic phased array inspection robot for non-destructive evaluation (NDE) is presented. The robotic system significantly will reduce manual labor over current inspection regimes, as well as enabling inspection of inaccessible/hazardous areas such as those found in the nuclear and petrochemical industries.

ELECTRONIC ARRAY PROBE FOR ULTRASONIC IMAGING
The Journal of the Acoustical Society of America, 2010An electronic array probe for ultrasonic imaging includes an array of transmitting and/or receiving electroacoustic transducers arranged in concentric bands in which the transducers are tangent to one other in both radial and circumferential directions.

Transducer arrays in medical ultrasonics
The Journal of the Acoustical Society of America, 1978Ultrasonic instrumentation based on linear and phased array transducers is increasingly being used in clinical diagnosis and yields information not hitherto available. However, the use of ultrasonic arrays is not necessarily restricted to diagnosis. They may, in the future, play an important role in therapy as well.

Ultrasonic phased array systems
The Journal of the Acoustical Society of America, 1980Ultrasonic phased array method and apparatus for the static or dynamic investigation of structures, such as organs of the body, or intra-uterine detail, wherein ultrasonic echo pulses, reflected back from a testpiece to one or a group of adjacent transducers of a linear transducer array, are converted to corresponding electric signals which are then ...

Array-driven ultrasonic microactuators
TRANSDUCERS '91: 1991 International Conference on Solid-State Sensors and Actuators. Digest of Technical Papers, 2002The authors present the design of an array-driven ultrasonic microactuator. Unlike a conventional ultrasonic motor, the array-driven ultrasonic microactuator consists of many distributed modules, using a concept similar to that of the distributed microactuator array. With a conventional ultrasonic motor, it is difficult to control an object locally and

An ultrasonic probe used for ultrasonic diagnosis apparatus. A plurality of ultrasonic transducer elements are provided in a convexity at the tip of a probe so as to constitute a convex array ultrasonic probe. The curvature radius of the convexity is set at not greater than 12 mm and the pitch of adjacent transducer elements is set at not greater than ...
