Phased Array Tutorial

Combined Image Formats

Phased array images are powerful in their ability to provide real time visualization of volumetric data. Through the electronic scanning process, imaging truly becomes real time and is used in both manual and automated systems to increase probability of detection. Especially in automated and more capable phased array instruments, the ability to display multiple image types and store complete raw waveform information for the entire inspection allows post-scanning analysis of the inspection. Because all the ultrasonic waveform data is collected, this post-analysis enables allows reconstruction of sectorial scans , C-scan and or B-scans with corresponding A-scan information at any inspection location. For example, the screen below simultaneously displays the rectified A-scan waveform, a cross-sectional B-scan profile, and a C-scan image of a set of reference holes in a steel test block.
