This webinar delves deeply into two advanced ultrasonic techniques onboard Evident’s Omniscan X3 64 - Total Focusing Method (TFM) and Phase Coherence Imaging (PCI). TFM, owing primarily to its focusing abilities, is effective in challenging applications providing improved resolution and accurate sizing. PCI, which is an amplitude free technique, has vastly improved the visualisation and characterisation capabilities for some of the most difficult to detect defects. Both techniques use the same elementary A-scans but have different advantages and limitations due to their signal processing methods.
The accuracy of imaging can be affected by material properties, object geometry, and the quality of the transducer. Additionally, it can be time-consuming and necessitates a significant amount of data processing. Understanding the fundamental principles behind these two techniques is vital for successful application in the field. This webinar aims to explain the theory and practical applications of these techniques and highlight their strengths and limitations.
