Abstract
Transmit-Receive Longitudinal (TRL) probes can be used for the inspection of noisy material, such as austenitic materials. By using various techniques, an inspection area is not constrained by a wedge design of an ultrasonic probe and the benefits of using a linear probe array (rather than a matrix) are maintained. Volumetric or TFM-like imaging on austenitic materials using a linear transmit array and a linear receive array that are out of plane with one another (a TRL configuration) and not in the main imaging place can simplify the inspection and analysis of such materials. For each scan position, an ultrasound probe can acquire acoustic imaging data. Then, a processor can then combine acquisitions from adjacent scan positions to create an imaging result using synthetic aperture focusing technique (SAFT) principles to recreate a focalization in a passive axis of the probe.
