Ultrasonic backscatter measurements using phased array ultrasonic transducers
The Journal of the Acoustical Society of AmericaDiffuse ultrasonic backscatter techniques are used to characterize microstructures and work well when grain scattering is confined within the single-scattering regime. When effects from higher-order scattering are present within the measurements, grain sizes are often overestimated.

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 ...

Quantitative ultrasonic phased array imaging
AIP Conference Proceedings, 2014When imaging with ultrasonic phased arrays, what do we actually image? What quantitative information is contained in the image? Ad-hoc delay-and-sum methods such as the synthetic aperture focusing technique (SAFT) and the total focusing method (TFM) fail to answer these questions.

Ultrasonic phased array controller for hyperthermia applications
Ultrasonics, 1991Multiple and mechanically scanned ultrasound transducer systems have demonstrated the efficacy of using ultrasound to produce deep localized hyperthermia. The use of ultrasonic phased arrays has been proposed as an alternative to these systems. A phased array offers a more flexible approach to heating tumours in that the size, shape, and position of ...

Ultrasonic phased arrays for nondestructive testing
NDT International, 1987Abstract Although ultrasonic phased arrays are potentially ideally suited to many applications in NDT, their use in practice is limited by the complexity of array probe manufacture and the bulk and cost of the associated electronic control instrumentation.

Pressure Vessels Inspections Using Ultrasonic Phased Arrays
Ultrasonic Nondestructive Evaluation for Material Science and Industries, 2003Phased arrays offer significant technical advantages for weld inspections over conventional ultrasonics. The phased array beams can be steered, scanned, swept and focused electronically. Beam steering permits the selected beam angles to be optimized ultrasonically by orienting them perpendicular to the predicted defects, especially Lack of Fusion ...

Optimization of Ultrasonic Phased Arrays
1998Ultrasonic phased arrays are an emerging technology in nondestructive evaluation (NDE) applications. A phased array is a multi-element piezo-electric device whose elements are individually excited by electric pulses at programmed delay times [1]. Such a delay scheme allows electronically controlled dynamic beam control.

DFW-YOLO: YOLOv5-based algorithm using phased array ultrasonic testing for weld defect recognition
Nondestructive Testing and EvaluationAlthough phased array ultrasonic testing (PAUT) technology has been widely employed in pipeline weld defect recognition, current defect recognition still relies on manual operation, which limits its efficiency.

Composite material ultrasonic phased array testing
AIP Conference Proceedings, 2019This thesis discusses the results of an ultrasound testing of a fiberglass plate using a flaw detector with phased antenna arrays. Fiber-reinforced laminated composite materials are widely used in modern light-weight structures. Non- destructive experiments carried out on the composite plate with artificial defects. The examined 5 mm sample was made of
