Fast total focusing method by a migration approach
2015 IEEE Far East NDT New Technology & Application Forum (FENDT), 2015The Total Focusing method is an efficient approach to perform ultrasonic imaging of industrial components. It consists in focusing at each point of a reconstruction area by applying coherent summations. The main issue of this method is the computation time which makes real-time imaging difficult for large images.

Improvement of the total focusing method using an inverse problem approach
2017 IEEE International Ultrasonics Symposium (IUS), 2017Imaging using the total focusing method (TFM) is a popular tool, which is becoming a standard, for nondestructive testing and evaluation. From full matrix capture data, it consists in focusing at each point of a defined reconstruction zone. It is generally more efficient than conventional phased array focusing, which only focuses at a few points ...

Insight - Non-Destructive Testing and Condition Monitoring, 2023
Ultrasonic testing of coarse-grained materials is strongly influenced by high-level scattering noise. In addition, the signalto-noise ratio (SNR) and spatial resolution of imaging by the traditional total focusing method (TFM) are relatively low. In this

A Study of Total Focusing Method for Ultrasonic Nondestructive Testing
Journal of Testing and Evaluation, 2013Abstract Commercial ultrasonic phased array (PA) systems can perform multiple inspections in real-time using array transducers. This approach involves firing array elements in a particular sequence to produce high-resolution images at a high frame rate with excellent signal-to-noise ratio (SNR).

Ultrasonic Inspection of Weld Defects Using Total Focusing Method
2021Ultrasonic arrays have been widely employed in industrial applications because of their ability to perform quick inspections for detection and characterization of flaws. The total focusing method (TFM) is an advanced ultrasonic imaging technique that utilizes the full matrix capture (FMC) data of the phased array elements to generate a high-resolution ...

Simulation of the Application of Compressive Sensing to Ultrasound Total Focusing Method Imaging
2020 15th Symposium on Piezoelectrcity, Acoustic Waves and Device Applications (SPAWDA), 2021In order to lower the sampling rate and to reduce the huge amount of data in imaging of phased array total focus method, an ultrasound detection imaging method is proposed which is based on compressive sensing. The “analog-information converter” (AIC) is introduced into ultrasonic phased array total focus method imaging system, which could recover the ...
