The Total Focusing Method (TFM) is an important step toward the future of Phased Array Ultrasonic Testing as it eliminates most of the artifacts caused by sector scans or linear scans. It uses standard phased array probes - but instead of using delay laws it uses Full Matrix Capture (FMC) to collect the data and the Total Focusing Method is actually the subsequent reconstruction technique to visualize the result. This video details some of the drawbacks/challenges of PAUT and how they can be solved using TFM.
A big thanks to Cyril Thibault from AOS (https://www.aos-ndt.com/) for the PAUT and TFM images.
