Total Focusing Method Based Ultrasonic Phased Array Imaging in Thick Structures [PDF]
Journal of Nondestructive Evaluation, Diagnostics and Prognostics of Engineering Systems, 2021 Abstract Ultrasonic non-destructive testing traditionally uses a conventional monolithic transducer. An approach similar to this comprising of independent single transmissions but with reception performed by all the elements in phased array ultrasonics is known as Full Matrix Capture (FMC).

Calibration of ultrasonic hardware for enhanced total focusing method imaging [PDF]
Insight - Non-Destructive Testing and Condition Monitoring, 2020 Experimental variation from ultrasonic hardware is one source of uncertainty in measured ultrasonic data. This uncertainty leads to a reduction in the accuracy of images generated from these data. In this paper, a quick, easy-to-use and robust methodology is proposed to reduce this uncertainty in images generated using the total focusing method (TFM).

On Dispersion Compensation for GAW-Based Structural Health Monitoring
Sensors, 2023 Guided acoustic waves (GAW) have proven to be a useful tool for structural health monitoring (SHM). However, the dispersive nature of commonly used Lamb waves compromises the spatial resolution making it difficult to detect small or weakly reflective ...

Multi-Mode Total Focusing Method (MTFM) to Detect High-Temperature Hydrogen Attack (HTHA) – A Review
Journal of Materials Exploration and Findings, 2023 High temperature hydrogen attack (HTHA) is a commonly observed harm component in carbon steels exposed to high temperature and pressure in a hydrogen-rich environment. Hydrogen together with carbon responds to produce methane.
