Existing defect detection tools using ultrasound rely on phased array ultrasound. In this method, many transducers are pointed in the same direction to generate an image of that specific area. This ...

RAILWAY AGE MARCH 2022 ISSUE: Welcome to “Timeout for Tech with Gary T. Fry, Ph.D., P.E.” Each month, we examine a technology topic that professionals in the railway industry have asked to learn more ...

Advances in ultrasound—the same imaging technology that uses sound waves to allow doctors to monitor babies in utero—are being applied by engineers at the University of California San Diego to make ...

Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and ...

A scanner ensures that ultrasonic probes stay properly aligned as they move over the surface of the inspection area. Scanners with motorized actuator arms, suction cups and adjustable, flexible tracks ...

RAILWAY AGE MARCH 2022 ISSUE: Since 2020, Transportation Technology Center, Inc. (TTCI) has been conducting tests to evaluate the capability of electromagnetic acoustic transducer (EMAT) ...

Engineering structures including buildings, pipelines and rails require periodic testing to prevent catastrophic failures occurring due to corrosion, impact, and strain. High-frequency sound waves ...

A high-efficiency circular vibration/polarization ultrasonic conversion technology capable of detecting cracks, which can occur in various directions within a structure, has been developed for the ...
