Multi-element ultrasound, or Phased Array (PA), is an advanced non-destructive testing (NDT) technique that uses multiple ultrasound elements within a single probe to generate dynamic, electronically steerable beams. This technology makes it possible to scan a wide inspection zone with unrivalled flexibility, while reducing the need for physical repositioning.

Thanks to multi-element ultrasound, it is possible to obtain detailed, real-time images of the interior of inspected materials, facilitating the detection of complex defects such as cracks, inclusions, delaminations and thickness variations. This method is particularly well suited to high-precision inspections in the aerospace, oil & gas and nuclear industries, where safety and quality are top priorities.
