In the medical applications of ultrasonic imaging, sound waves of high frequency are usually employed to produce in-depth cross-sectional images of internal organs. Special multi-element transducers ...

A popular and nondestructive technique is generally employed to calculate the thickness of a material from one side. This technique is called ultrasonic thickness gaging. In the late 1940s, the first ...

This PhD project explores the development of a robotic, ultrasonic non-destructive testing and evaluation (NDT&E) system to evaluate and characterise composite and polymer materials—widely used in ...
